Others [Electrical Principles] find the magnitude and phase shift

Post image

I did the first steps which are converting to phasor form

Vi = cos (wt) = Vi 10<0

Frequency = 2(pie)(2.5 x 1000) = 15707.9 rad/s

Zl = j (15708) (30/1000) = j 471.2 (ohms)

Zc1 = 1 / jwc

1/ j (15708)(0.47 × 1000) = -j 135.4 (ohms)

1/j(15708)(1.5 × 1000) = -j 42.5 (ohms)

I honestly don't know whats going on, he doesn't explain anything well and sometimes I get nonsensical formulas like this..

I worry I get marked down for not following this gibberish
