I have the following problem and I'm not sure if I did it correct:
Given v(t) =10 + 5 Sin (377t+30 degrees) - 7 Sin (377t-45 degrees)
Find VRMS
Putting them into rectangular form:
(7.07 + j 0) + (3.06 + j 1.77) - (3.5 - j 3.5)
now I add my reals and imaginaries and that's my answer? Or I can convert that number into polar as well.
