hey, thanks young vito. been lookin for something like this as well, bin tryin to figure out sytrus for a while
when the guys talkin bout the slop of the sin wave, its the differential. the differential of the sin wave is cosine wave, so it modulates of the position at the cosine wave, (the slant/slope of sine wave)
dunno if that helps any1, or confuses any1 even more. sorry if it does
