Originally posted by thegunner i know, thats why im doing poorly in that class, it *****, st least my teacher is easy, otherwise id proly have a seriously low F. i wish i hadnt taken it cause i didnt need it even. i had my math credits taken care of last year. next semester instead of precal im doing theater practice. i think that will be fun, and a good friend of mine was in it first semester and loved it so hes taking it with me second semester.

Let me see if I remember correct

y/r= sin

x/r=cos

y/x=tan

r/y=csc

r/x=sec

x/y=cot

Am I right???

yeah, thats right, i just have trouble with the double angle and half angle identities,

cos2(thetaA)+(thetaB)=cos(thetaA)cos(thetaB)-sin(thetaA)sin(thetaB)

those ones blow
