Homework Statement
Hi guys,
I don't know if this should go here because it is an excerpt from a higher level problem. The part where I get stuck is when I try to add the cosine functions.
Is there any way to add sine and cosine functions that have a scalar in front that cannot be factored out? For example:
5*cos(wt) + 6*cos(wt + pi/4)
If there weren't any numbers in front of the functions then I could use the trig identity. What can I do with the numbers there? Thanks
