The book we use in class uses very basic examples and my professor loves to just give us little twists and make our lives a living nightmare. (A joke but he does this a lot and it gets real annoying).
I have v(t) = -4 + 3sin(2t + 35) + 2 cos(3.14t +10) + 2cos(2t -64)V
I want to know the RMS value and the average value.
My first logical answer for average value was -4, because the integration of any sinusoid over a period is 0.
For my RMS value, I divide the amplitude of every sinusoid by the SQRT(2) then I square them while also squaring the (-4). I now sum all those values and take the SQRT of the sum to find my Vrms. Which is 4.97.. Volts.
I need confirmation if this is right or just absolutely incorrect. If the latter I would love some guidance.
