I came across this problem in the "series and parallel ac circuits" worksheet and did not know how to go about it. Can anyone walk me through the problem?
Determine the input frequency necessary to give the output voltage a phase shift of 40 degrees
The circuit is an ac voltage source, with a 0.01uF capacitor and a 2900kohm resistor in series with the source (see problem 3 on http://www.allaboutcircuits.com/worksheets/ac_s_p.html)

Use the formulas for reactance of a resistor and a capacitor.
Then use phasor arithmetic to sum the impedance of the resistor and the capacitor.
