Incorrect Resonance calculation

[LostRobotMusic]

The line of code that says double alpha = sin(w0) * (2 * q); is actually supposed to say double alpha = sin(w0) / (2 * q);. The typo makes the resonance knob have the wrong value.

I was also curious about this as it seems it should be a divide and not a multiplication. Can anyone confirm which is correct?
