RLC parallel circuit, complex numbers, done it but not sure

hello all,

been a while!

i have just started my HND electronics course and i have to do some circuit analysis.
i have a parallel RLC circuit. three components, R = 12k ohms, L = 10mH, C = 10nF
with a 10sin(1000t) supply
i have to find the total impedance in polar form
supply current in polar form
current through each component in polar form
q factor
bandwidth and
resonant frequency

i written out what i have done and attached it (hopefully)

not sure about this. i think that i may have done something wrong with the angles.

thanks

simon

Re: RLC parallel circuit, complex numbers, done it but not sure

The problem seems to be with C which in nF is almost a short circuit. Check whether it is
