General Sine Wave
y=sin(x+90degrees)
For this thee amplitude would be just one because it is not shown. The period again would also be one, whereas the phase shift would -90degrees?
To graph this would i substitute x with values of an interval of my own choosing between 0-360?
I am confused also as to how to start to graph once the amplitude, period and phase shift are known

Amp = 1 Period = $\frac{2\pi}{1} = 2\pi$

Phase shift -90, just graph $\sin x$ and move it to the left 90 degrees or the length that is 1 quarter of it's period.

does it matter if you use radians/cycle or degrees/cycle?

Higher math courses use radians but it does not matter, just remember the following relationship

$\pi^{c}= 180^{\circ}$
