I calculated the phase shift of the output voltage with respect to the input voltage. Phase shift = - 38.055 degree at frequency of 1000 Hz between the input and output waveforms. Would you check the final answer for me, Please?
I'm asking this question because I would like to learn how to calculate phase shift for simple practical circuits such as low and high pass filters.

I used these equations for calculating phase shift:

XL = 2 * PI * f * L
Xc = 1 / ( 2 * PI * f * C )

Z1 = R1 + J * XL
Where, J is the root of -1

Z2 = R2 in parallel with (-J * Xc)

Then I used the equation of voltage divider.

 

Find Gain=Vout/Vin=A+j*B→tg(fi)=B/A → fi=arctg(B/A)
