Homework Statement
Alrighty. I have reduced a vibrations problem to an integral and I am having some trouble
evaluating it.
I have a value for t and need to find:[tex]-c\omega^2Z^2\int_0^t\cos^2(\omega t-\phi)\ dt[/tex] (1)I guess it is just my memory that is the problem.
If I had [itex]\int\cos^2(x)\ dx[/itex] It would not be a problem.
I am thinking now that I type this that a simple U substitution should do the trick right?EDIT:
If I let [itex]u=\omega t-\phi\ \Rightarrow du=\omega\ dt[/itex]
So (1) becomes:
[tex]-c\omega Z^2\int_0^t\cos^2u\ du[/tex]
Yes?
