How can we apply the doppler effect when the source of sound is coming towards us at supersonic speeds?Is there a mathematical method for it?

The velocity of the source is built into the Doppler formulas. Plug it in, see what happens. I imagine the source would hit you, you would die, then the sound would arrive and you'd be too dead to hear it.

The frequency comes out to be negative.How is this possible? o:) Assume that I am alive to think about this.
 
The frequency is negative because the first noise you hear is the last one the source made. The source will always be emitting ahead of the last sound it made.
