if u cant think of way of doin it, just keep subin in t values!

note- the graph is y=2cos(x-pie/4)

Standard cos curve but:

Amplitude becomes 2 because A is just the coefficient before the cos.

And then it shifts to the left by pi/4 because it's got "-pi/4" in the brackets.

Yay.

You could use wolfram alpha :]
