Thanks Mr P; BUT
: How you wonder? Use a series representation of sin(t) and
: cos(t). I will not do it here because it is easy to do but hard to
: format. Just write out the first few terms of the series for cos(t)
: then use everyones favored derivative equation and you will start to
: see that you are generating the terms for the -sin(t) series.
it's this "sin/cos" stuff I'm not familiar with (as you say).
what is "a cos/sin series" ?
