1. ## Simple Harmonic Functions

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

and in this form:

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

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

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

or

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

thanks for any help

2. Hello,

The first function has nor period neither amplitud.

The second has a period : $2\pi$ and you can only find the max of it.

3. great thanks, I wish my teacher would explain this, (or book), why does the second function have a period of $2pi$ though? can you find the phase shift? -thanks
