 Explaining |  I am so lost!!!! In Trig. class we were learning how to use trigometric Identities. I am so lost!! She gave us a problem like this one. sin^3 x - cos^3 x= (1 + sinx * cosx) (sinx - cosx) Then she told us to use the reciprocal, quotient, and pythagorean indetities to symplify the equation, to where there is only 1 trig. finction left. I know how to use the identities but I do not understand how to use them to symplify and equation like this. can some1 plz help me, I am so lost! ---------------- psalms 23 The difference between genius and stupidity... genius has its limits.  | |
