Question 923952: T-table for graphing sine/cosine graph? I understand most of this image. I have to do this without a calculator that's why I have to set this up with a t-table. From the image I just need to know where to 4π/4 comes from and why the phase shift goes from π/2 to 2π/4 I understand the rest it's just those two parts that make no sense to me.

you have
=> in your case ,, and
Both and in these graphs affect the phase shift (or displacement), given by:
=> in your case

you can write as or , and that was used because values
The choice of the values of in the table correspond to and intercepts, maxima and minima points.
