Graphing a sine function while interpreting the values of A, B, C and D, yielding amplitude, period, phase shift and vertical displacement of the cosine graph.
@lebrondurant635 Hello again, it would be |C/B| if the function was in y=Asin(Bx-C)+D format - but in our example, B has already been factored out. So we have y=AsinB(x-C)+D instead, which gives us C as the phase shift... In this case, pi/4. So the video is actually correct. Check it with your teacher if you'd like. :)
because the formula for getting the phase shift is |c/b| in this case it is |-pi/4/2| (the abosolute value of pi over 4 divided by 2) the result is pi/6 :) hope it helps
thanks for the tutor

Don't you have to multiply pi/4 by 2 since the equation has 2(x- pi/4).

@lebrondurant635 i stand corrected. it should be pi/8 :) peace!

this is wrong! phase shift should be equal to |c/b| your phase shift should be pi/6 not pi/4
