Trigonometry - Graphing transformations of sin and cos

Starting with a basic graph of sine or cosine, you can begin to make transformations of it. This includes shifting, stretching, and reflecting. By reading the equation carefully you can figure out what the new graph should look like. This is where we find the amplitude, period, phase shift, and vertical shift.

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 👏

[@MySecretMathTutor]

Some of my videos have been around a while, but as long as they are still helping people I'll keep them around. I'm still here too, so its all good. :^D

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

[@multione8180]

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

[@MySecretMathTutor]

Wow, thanks! :^D

[@ashishtiwari1912]

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

[@kendra4912]

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

[@rajendramisir3530]

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

[@DoctorFashion]

Well explained ., thank you

[@particleonazock2246]

This video TRANSFORMED my life.

[@DrLiangMath]

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

[@hectorviesca3459]

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?

[@Alistlessbeing]

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

[@zoeliam898]

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

[@malakaly5711]

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

[@PSYCHOSENSI]

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

[@tasneemnezami518]

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

[@tomgeorge1244]

Fantastic job at explaining!!!

[@ssxratched6128]

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

[@coll2006]

You made this very simple. Thank you.

[@rohanrao1734]

Decently helpful video thank you

[@vintagesparkles4289]

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!

[@guillermogarciaferrer9601]

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

[@nr4611]

Thank u sir,very helpful video

[@dinisiregar5304]

Thank you , this video make me understand about this matery

[@nilahkohistani7749]

this just made everything make so much sense

[@SW-2010]

This was very helpful, ty.

[@binabansal1605]

Awesome explanation 🙏

[@jackanderson3092]

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

[@yceklascab]

same

[@futuredr.7815]

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

[@jaredbrooks2226]

Great Vid man. Jesus Bless you.

[@milenelopes13]

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

[@scarlettmartinez8438]

Milene da Silva because the original equation is Asin(bx-c)+d you have to make it c a negative, just like the original equation. And the same thing for d, if it’s negative you have to make it a positive since d in the original equation is positive. Hope that made sense.😊

[@cussmemo1921]

I honestly love you

[@oliviali623]

That helps a lot thank you!!!!

[@iamsomeone8266]

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

[@imfhr]

best explaining

[@ay7565]

You saved my life thank you!!!!!!!! 😭

[@tharaniikumarvelu6013]

Yes yes ...my life too ..thank you very much

[@williamsatterfield2852]

10:13 why did he make c negative?

[@leochao2594]

since the original equation has a negative sign in front of c, if it appears positive, the phase shift is negative.

[@aloroasuman9118]

Explained well

O my goodness your so helpful

[@HarpreetSingh-jd3tu]

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

[@lalygtr2576]

God you are so good. Papa bless

[@holup7025]

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

[@MySecretMathTutor]

Sounds like a great idea, especially to get a few key points to start the graph. :^D

[@nahdeashahzad3844]

Ily man

[@pepplow]

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

[@MySecretMathTutor]

Hi Richard. I'm assuming you mean at 11:53. To add these pi's you want to find a common denominator. This is where the 2pi becomes 4pi/2. The top and bottom was multiplied by 2. Now with a common denominator, the tops can be added strait across.

[@pepplow]

@@MySecretMathTutor thank you so much for replying.
