    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}
