    Proving the Angle Relationship in Complex Vector Multiplication

    Many thanks, Using the relation tan(θ1+θ2)=(tan(θ1)+tan(θ2))/1-tan(θ1)*tan(θ2) I was able to use trigonometry(SOHCAHTOA as i learned it way back when) to plug in for the tan(θ1) and tan(θ2) which ultimately leads to the solution I was trying to prove from my first post. :smile:

    Proving the Angle Relationship in Complex Vector Multiplication

    I mean I'm actually a senior physics major :P(slightly embarrassing I couldn't solve this) I've seen Euler's identity and it is introduced in the chapter, so I suppose that could be a viable way to solve the problem.

    RLC Series Circuit Problem: Find V_source from V_R, V_L, V_C

    Homework Statement In an L-R-C series circuit, the rms voltage across the resistor is 32.0 , across the capacitor it is 90.1 and across the inductor it is 51.5 . What is the rms voltage of the source? Homework Equations Well there are lots of equations V_rms =V/sqrt(2) V_R=IR...
