I have the following problem.
Find expression of V3 in sine waveform
This is what I have.
R^(2)= 3^(2)+2^(2) a=arctan 2/3
R= 3.60 a=33.69 degrees
When looking at the required criteria it says to use the compound and double angle compound formulae. I'm not to sure how this would fit in, any help would be appreciated.
