NEW DIGITAL SAT FORMULA VIDEO HERE: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PlgbXGyKBYw.htmlsi=SnXpLy7XLkquT_rg

Best of luck to us all, hopefully the exam tomorow is easy

formula 1 - slope of a line - m=y1-y2/x1-x2 formula 2 - slope intercept form - y=mx+b where m is the slope and b is the y intercept formula 3 - point slope formula - y-y1=m(x-x1) where m is the slope of the equation formula 4 - midpoint formula - x1+x2/2, y1+y2/2 formula 5 - distance formula - d=square root(x1-x2)^2+(y1-y2)^2 formula 6 - length of an arc - L=(n/360)2pir where n is the central angle and 2 pi r is the circumference of the circle formula 7 - area of a sector - A-(n/360)pi r^2 here the n is the central angle as well and pi r^2 is the area of the circle formula 8 - quadratic formula(this one is written on his t shirt as well) - x=-b+- root(b^2-4ac)/2a here a,b and c is derived from the normal formula ax^2 + bx + c and b^2-4ac is known as discriminant as well, if it's value is less than 0 then no real solution exists, if its value is equal to 0 then only 1 real solution exists and if its value is more than 0 than more than 1 real solution exists formula 9 - trignometric formula - sohcahtoa where sin theta = opposite/hypotenuse, cos theta = adjacent/hypotenuse and tan theta = opposite/adjacent formula 10 - probability - numberof favourable outcomes/number of total outcomes formula 11 - circle equation - (x-h)^2 + (y-k)^2 = r^2 where r is the radius of the circle and h,k are the points located at the centre of the circle formula 12 - exponential growth - y=a(1+-r)^t where a is the initial value, r is the rate of growth and t is the time taken for growth plus has to be used inside the bracket during exponential growth and minus sign has to be used inside the bracket during exponential decay formula 13 - vertex of a parabola - x=-b/2a where b and a can b found from the formula ax^2+bx+c formula 14 - vertex form - y=a(x-h)^2+k vertex here is the h,k and a tells towards which side will the parabola open up If a > 0 the parabola opens upwards, resulting in a minimum value. If a < 0 on the other hand, the parabola opens downwards, resulting in a maximum value. formula 15 - pythagoras theorem - a^2 + b^2 = c^2 where a and b are the legs of the perpendicular angle and c being the side opposite to the 90 degree angle formula 16 - distance = rate x time where rate and time has to be in the same unit formula 17 - relation between sine and cosine - sin(x)=cos(90-x) formula 18 - sum of solutions of a quadratic formula using the normal formula - ax^2+bx+c, sum of solutions = -b/a, product of solution - c/a formula 19 - area of an equilateral triangle - s^2 root3/4 where s is the side formula 20 - some common pythagorean triplets - 3,4,5 and 5,12,13 and 7,24,25 and 8,15,17 the multiples of these numbers can come as well in the exam formula 21 - perpendicular slope - the perpendicular slope of a slope m=a/b would be its negative reciprocal for example a/b becomes -b/a formula 22 - sum of angles of a polygon - (n-2)180 n being the number of sides of the polygon formula 23 - this one was not there in the video but i am mentioning because its important keeping sat in mind - converting degrees into radians - 'Radians = Degrees × π/180 Go and ace the sat first, thank me later :))

Good luck to everyone taking the SAT tommorow

Very comforting that I’m not the only one binging his videos the day before 😭😭 good luck guys we got this!!!

You're a lifesaver. Through and through. Period.

Best of luck guys, I'm so damn nervous.

Hope everyone will perform best on tomorrow's test Best of luck guys also to me ;) honestly quite scared SAT oct 2021

Just remember that no matter how you guys do, I will be proud of you

This calmed me down so much😭 thank you❤️ ALL THE BEST EVERYONE

Taking the sat tomorrow 😭😭

Best of luck fellas❤❤😭

Thank you so much! We really appreciate your efforts ❤️❤️

Thank you so much! Good luck everyone 🙏🙏✌️👏🥰

Dude you can't imagine how helpul this was. Thank you so much.

This was good to watch, thank you!!

Thanks so much you have helped a lot!

Thank you soooooo much!

Thank u huzefa ur the best all the luck for us in oct 2!

you are the best teacher i have ever seen thank you

This was so helpful, thank you so much for taking the time to put this together!!! I'm so glad I found your channel!

I think it would be helpful to say opposite reciprocal instead of negative reciprocal when finding the perpendicular slope. If the slope is already negative and you want the perpendicular slope, you might get confused. My teacher always advices to say opposite reciprocal.

Am taking mine today ❤️😌 thanks for this

Dude, that was so amazing. I am subscribing right now!

Im writing tomorrow; I started prepping 2 weeks ago and got a 1500 in my practice test , and I practiced again yesterday and got 1200 , now here I am...

Hoping to clutch an 800 on math tmrw good luck

How can you be so detached For a long time Always awaiting for you crucial videos about SAT Finally with a best one.

binging this the night before the SAT. ...yey 😭

Extremely helpful

Bless you man! ❤️❤️

damnn i remember studying for this a few years back. I just wanted to say good luck to anyone that got upcoming exams, don't stress🖤

Thank you so much my dude

Good luck tomorrow everyone

thank you very much for all those informations

Watching this right now before I take the exam💆🏽‍♂️

Thank you very much, bro. I just watched all these 4 videos before my today’s SAT, and I am completely sure that thanks to them I will have a perfect 800 for Math section:)

Good luck everyone

Another great video, when are you going to do SAT writing videos?

You always come to the Rescue

You were literally the best tutor that i have ever seen in my life. Thank you so so so much for your help, for your RU-vid videos and for your free help for those who really need it. I wish you all the best!!!

Thanks a lot bro, helped a lot really❣️❣️❣️😘😘😘

so very well explained.

good luck everyone!

Thanks king ♥️

Woah love the intro

Thank u so much for this video a big portion of these RU-vid videos are way to long and you get right into the chase 💀 Hopefully everyone nails their sat 💪🏽 March 2022 sat . 😪

Thanks sir its really help ful

Amazing bro

I have one week let’s get it!!!

tomorrow is my sat I hope I do well !!!

Taking SAT tomorrow and I expected to see the sequence formulas

2 hrs till the exam and this definitely boosted my confidence. It's such a well-done video. Thank you !!!

taking sat tomorrow with 4 hours of preparations, i am definitely cooked

Anyone on Oct 1st sat?

waiting for entry ....

Thank you for the clear and to the point video…. Do you have a link to these formulas slides you used as a file so we can print them out?

10 MINUTES BEFORE THE TEST, GOOD LUCK GANG 🤘🏼

Sitting at the test center and watching you... thank you so muchhhhh for helping us out.. hoping to get 750+😭😭

I have sat tomorrow

slope is y2-y1/x2-x1

Suggest me a website or whatever where I can study all SAT materials easily

@Scalar Learning 8:29 Does the equation have to be set to 0 to find sum of the solutions and the multiples of the solutions? or can it be y= ax2 + bx +c

I’m from 2024 and I have the sat test tomorrow 😭😭😭

Slope a line is y2-y1/x2-x1. Not : y1-y2/x1-x2

Commenting my before and after for tommorows test, reply to know my score in 2 months!

Slope formula y2-y1/x2-x1

How can I register for lessons with you tell me the procedure

is the slope of a line formula entered incorrectly? because I was taught that it was y2-y1 / x2-x1

Thank you. I'll tell you my math score in 2 weeks

December 2021 gang

Isn’t the Pythagorean theorem the same as the distance formula?🤔😲

my exam is in 30 mins 😔

Good luck for 27 AUG ✌️

4:43 lol I don't need to learn SOHCAHTOA.... As I follow like this SinA = P/H , CosA = B/H.... P= Perpendicular B=Base H=Hypotenuse eelo Beta Peelo are Hare Bol (OR) (P B P H H B) Pandit Badri Prasad Hi Hi bol I don't think there is much difference between them and this is much easier than the SOHCAHTOA and others I find....Anyway everyone has their own ways. Well most Indians would understand this.

Anyone cramming for the SAT right now??

I just want a 750 minimum

11:09 Has this equation ever shown up in a test? It feels kinda niche and useless...

Hello! Very good! I think you will be interested in what other way you can solve quadratic equations (it can only be used when a is 1): x^2+4x-12=0 by the theorem, the inverse of Vieta's theorem: [ x1 + x2 = -b; x1 * x2 = c] x1+x2 = -4 x1 * x2 = -12 and now we need to find such numbers instead of x1 and x2 so that they fit into both equations : x1=-6 and x2=2 -6+2=-4 (right) -6*2=-12 (right), So x1 = -6 and x2=2. If you figure it out, you can solve the equations in this way in a couple of seconds:)

Whos giving their exam tomorrow???

Ty also may I know if you are muslim?

5 days and im starting :skull:

The paper was difficult from practice test

WOOOOOOOOO SAT IS TOMORROW HOPE I DONT DIE AHAHAHAHAHA-

0:50 Isn't the formula for slope of the line = y2 - y1 / x2 - x1 ?

1:55 why isnt it (-3,4) if there is a negative in front of the 3?

In the chapters it says SHCAHTOA...

The slope formula is wrong. It’s y2-y1 divided by x2-x1.

How was it? Reading section was little bit hard for me but I think I nailed the Math section!

u forgot 30 60 90 triangle

Pls tell me that I'm not the only one still studying btw my test is tomorrow

Is anyone else taking the sat on May 4th? LOL, I'm cooked

Sohancoa

Man he blinks a little too much, it is distracting. nice video btw, it helped greatly

If you see this comment and it has been more than 5+ months from it:) please reply so I can come and remember how stressed out I was the night before SAT!🤚🏻 Good luck anyone taking it tomorrow!

Is it just me or his intro sounds like a character named Spectre from Call of Duty Mobile??

Thanks . You are our hero 🫶🏻
