Phase Shift of Sine & Cosine Graphs (Sinusoidal Waves) - [2-21-13]

In this lesson, you will learn how to write down and understand how to phase shift a sine and cosine graph. This is important when we use sin and cos to write down a traveling wave such as an electromagnetic wave. These phase shifts will be used to mathematically describe how sinusoidal waves travel. This is used in engineering, math, and science fields.

Man, I wish you were my teacher back in the day. You make this so easy to grasp. Thank you so much.

Where were you when I was at tutorial....Thanks!!

Mr Gibson i just would like you to know that you are the only reasons i am passing my exams thank you so much sir

Ngl this is one of the most useful channels on YT 👏

Hi Mr. Gibson, Thank you for another great video! I was wondering if you would cover some aero/rocket science and the mechanics of it in a future video? Thanks

This is how math should be learned. Instead of memorization, we should be learning the "why?".

Yes, the phase shift of pi or 90degres, the waves cancel each other, kkkk I remember that now, wow has been while! Thank you again!

I’m about to take calc 1 for an EE so I’m trying to think about this in those terms. To be clear the phase shift of pi/2 is specifically a quarter period so if a period was 1/60 of a second (60hz) it would be 1/240 yes??

Thak you Sir, you are truly a master of teaching! By using different words and views your subjects come across crystal clear 😀

Hello Mr, Gibson. If i sign up on website will i access all high school science courses covered fully. in otherwords are the math, chemistry and phy and biology ful highschool courses? thanks

Awesome video! But you didn't cover what happens when you have both a frequency (or period) change and a phase shift. There seems to be something special about it, which for the life of me I've not been able to understand. E.g. if you have Asin(Bx+C) then somehow the phase shift is not C but C/B. Haven't been able to find an explanation of this that really clicks.

Hello Good Morning Sir . Sir I wanted to ask whether are these recorded dvd videos or you're making new videos each new day

[niyonkuruidrissa]

So helpful 10sir and much respect 💕💕💕💕

It may be better explaind by making table of X and fx for different values of 0 pi/2 pi 3pi/2 and 2 pi

Can you make a video on tangent csc and sec graphs pls!

I think phase shift of 180°, is also termed as phase inversion.
