Don't forget to rename the sine and cosine. Draw a circle with its centre, looks a bit like a titty no? Now draw a slanted line from the center intersecting with the circle, the vertical and the horizontal deflection are the sine and cosine for this angle. Now plot the sine as a function of angle. Looks like hanging boobies no? Sinus = breast, bossom, tits, ... . Now plot the co-sine function... looks like breasts again, ... but the other kind of breasts. So co-titties... or co-sine... Then there's tangents, ... touching the breasts...
