Trigonometry - Graphing transformations of sin and cos 

I realize these are older vids, but you are literally so helpful. My pre calc teacher is useless and the way you explain the concepts just really helps me understand it. THANK YOU 👏

Your methods get easier as the math gets harder.great content.

You sir, are one of the best teachers out there direct and simple No complicating the subject like books do You earned a sub

This video was SO helpful, thank you! I did not understand this much until I watched this video, but I completely understand now. Thanks for breaking it down step by step

A must seen video by Math and Engineering college students. Simple step by step instructions and explanation. Thank you Sir.

That helped a lot..thank you..I wish these kind of videos were available when I was in school.

This video TRANSFORMED my life.

Well explained ., thank you

the explanation on B and C (period and phase shift) is very clear!!

Your explanation was so systematic, clear and easy to understand. Thanks👍

Your explanation is excellent 👏👏👏👏 I appreciate your hard work ❤️ thank you

Fantastic job at explaining!!!

Awesome explanation 🙏

You made this very simple. Thank you.

this just made everything make so much sense

Thank you , this video make me understand about this matery

That helps a lot thank you!!!!

Thank you sir.

Thank you!!!

Thanks, it was super helpful. Can u make other video and tell us about the key point u mention in this video?

Watched this right before my math test😂 well explained teach👌🏽

Thank u sir,very helpful video

Very helpful 👍🏻

This was very helpful, ty.

Well done!

Decently helpful video thank you

Man, idk if this guy is gonna see this but you're saving me from my exams

You saved my life thank you!!!!!!!! 😭

thank you sir, this made perfect sense!!! how my precalc teacher instructed us, is he would have us do the graph of 4sinx first for a problem like 4sinx + 3pi/2. then he would have us do the left shift of 3pi/2 by having us move all the points of the 4sinx graph to the left.... (we were not introduced c/d for some reason!?) it is very tedious and time-consuming in my opinion compared to your easy method and i will utilize it on the test tomorrow :^) hope you're well!

O my goodness your so helpful

Good explanation. I still don't understand when I am ever going to use this in my life

I honestly love you

Thank you so so much!

great video, it really explained a lot for me but one thing i have a problem with is, wouldn't you move the phase shift horizontally to the right being that it is negative 3pi/2?

Explained well

best explaining

thank u

these were great. But I wish you included how to calculate the intervals, it’s required for my class

Why did you divide pi/2 by 4 when you can just move it over pi/2 instead of over complicating things by moving it pi/8 at 14:14

Great Vid man. Jesus Bless you.

I LOVE YOU

@9:13 why does the point start at one but when shifted up to 2 is at 2?

Ily man

for those people who are wondering which angle 2 pi represens sin = cos= 360 (degrees)

At 10:50 I don't understand why you made it negative?

10:13 why did he make c negative?

God you are so good. Papa bless

Bros my saviour

why did he put 4 PI at 12:14min mark?

16:24 would it be wrong if i would divide 5pi/8 by 2 to get the halfway point?

I dont understand how did he add the pies? someone help.

Haaaaaa makadxiya weduwe iiiiii haaaa ndabvuma ii🙈😂😂
