www.freemathvid... I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exaclty how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework.I post all of my videos on youtube but if you are looking for other ways to interact with me and my videos you can follow me on the following pages:

bro some teachers really do be wild.. they could literally just discuss one lesson like “what’s an atom” and what appears on the test is “explain the entire existence of the universe using the mass of the sun”

This video is a decade old, but its timeless! Super helpful thanks so much!

thanks

@drewalexis7424 10 лет назад

what buttons do you press on the calculater when you type in your inverse Cos, Sin, and Tan? I have a TI-83 calculater and im doing the problems youre doing and the wrong answers are popping up.

@Naturebeautifaul Год назад

Hey! Make sure your calculator is in degree mode first of all.

😮 SIRRRR YOU ARE AMAZINHG, I'M FAILING SO BAD AT AMTH BECAUSE I DON'T UNDERSTAND THE LESSONS BEFORE YOU CAME INTO MY LIFEEEEE THANK YOUUUUUU

What if u don’t get the same answers

@Pit_Winder 7 месяцев назад

I am actively losing it and this video is not on the test so why the FUCK did google show me this video as if it was what I was looking for. I'm giving up on this school shit.

good math XD

@Darshan91530 11 месяцев назад

Thank You Sir. I am in 7th class still I can understand this with your explaining methods.

@journeybrown112 Год назад

I don’t know how to plug that in to my calculator. I’d like to know how to do this without a fancy calculator with my brain or at least what buttons to hit. I just need the angle for a project but everyone uses a calculator and doesn’t explain how to use the stupid thing. Not fresh out of high lol it’s been a couple of decades.

how are these numbers coming out of your calculator mine evaluates sin^-1 (72/97) as 0.836448659158, not 47.9.

@lannenpa37 Месяц назад

Walmart will only pay for degrees or certificates that relate to working at Walmart. They have a variety of degrees that are in-scope but almost positive they are not going to pay for nursing.

What the hell is "Inverse Tangent" and "Inverse Sine?" How do you figure those?

@hikmetnasirov8494 Год назад

the best explanation so far i have heard from everyone my teacher explained not very clearly tysm :)!!

@hannahjacobs4972 2 года назад

You know I also see adds that say still using youtube for help? But I have been watching this guys videos for years now and he explains it way better than the way I am taught so yes I will always use youtube specifically Brian McLogan for help!!! 10/10 make sure to watch his videos

@Just_A_Ball_of_Tissue 6 месяцев назад

I guess this is where I use sin tan cos from the calculator

I'm building a pergola with a slope. This helped a ton to find the angle of slope! Thank you brought me back to trigonometry days ♾️

@maramneinaa6648 3 года назад

What if there isn't a right angle in the triangle and it's only an isosceles trig bcz of the lenghs

@brianmclogan 3 года назад

Would need to use law of cosines

@Oldag75 2 месяца назад

I finally realized that to solve such problems, one must know the numeric values of the trig functions for the given angles -- after which it's mere algebra. If you don't have an appropriate calculator, the values are available in tables. (Who made those tables?) I recently read that trig was used by the Ally POWs in The Great Escape, to determine the distance outside the barbed wire they would have to tunnel to reach the woods. That would be a great example to give to high school students, on the first day of trig class.

@lucygriffiths3306 Год назад

Please specify that you are working with a right-angle triangle. I wasted time watching the whole thing assuming you'd address 'triangles' as you said.

@Claudaraderie Год назад

About 15 seconds into the video he specified that this only works on right angled triangles. He did clearly state it early on

If I were to have a problem that had me find both the theta and the other angle like x is theta then you have your 90 and then I needed y how would I go about that
