Hello everyone,

I have a question regarding simple harmonic functions.

I know how to find the Amplitude, Period, Phase Shift ect. when the problem is in this form:

$\displaystyle

f(t)=a*cos(2t)+b*sin(2t) $

and in this form:

$\displaystyle f(t)=a*sin(2t)+b*sin(2t)$

but how can I find the Amplitude, Period, Phase Shift ect. when the problem is in this form:

$\displaystyle f(t)=t+sin(2t)$

or

$\displaystyle f(t)=a*cos(t)+b*sin(2t)$

thanks for any help
