What is the resonant frequency of a 1.0uF capacitor and a 15 mH coil in series?

Answer is 1.3KHZ

$\omega_R = \frac 1 {sqrt{LC}}$

$f_R = \frac{\omega_R}{2\pi}$

the formula of resonance frequency is
fr=1÷2π√ LC

fr = 1.3kHz

Unfortunately, copying and pasting don't work very well in this forum. I'm assuming you were trying to write

$f_r=\frac{1}{2 \pi \sqrt{LC}}$

which is the same thing as what I already wrote above.
