Amp = 1 Period =
Phase shift -90, just graph and move it to the left 90 degrees or the length that is 1 quarter of it's period.
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
