[maxmsp] differenciating trigonometric function with delta~

Hi list,

I was confused by the use of delta~ :
wanted to differentiate a cosine to get a sine~.
I thought i would need to multiply the output of delta
by 44100 to approximate derivative by finite difference..
but found out I had to multiply by some 6900 or so to
get the amplitude of my sine wave to have unit amplitude...
Am I blind about something ?
