TI-M: Re: Math Help
dude, if you are in calculus, you should be able to do this.... think trig
for the first one. (remember chief sohcahtoa?) you can just GRAPH the
second one. remember what cosecant is? 1/sin maybe? (no, not sin^-1,
that's arcsin) Dude.. Slope interecept form isn't hard either. something
like y-b=m(x-a), right? you really should crack down and learn this stuff,
or you are't going to do good. this doesn't sound like calc at all, anyway.
it sounds like precalc. DO IT BY HAND FIRST! don't rely on your 89!
