Best ResponseYou've already chosen the best response.1Oh, my pictures got cut off, but the math is easy to see if you know definitions of trig functions and basic algebra skills.

Best ResponseYou've already chosen the best response.0Yes I can see. Thanks for writing out the equations. So the answer would be A. sec^2 theta?

Best ResponseYou've already chosen the best response.1Tan^2theta + 1 = sec^2theta This is very useful to remember.

Best ResponseYou've already chosen the best response.0And can you check a question? The question is Which expression is equivalent to cos(pitheta)? I got cos theta. Is that right?

Best ResponseYou've already chosen the best response.0Oh ok. So since cos^2 theta can be crossed out, you move the 1st numerator over the 2nd denominator. That makes more sense. Thanks!

Best ResponseYou've already chosen the best response.1Well, it's not being crossed out. It's cos^2 theta divided by itself which is one. And then as fractions go, numerator times numerator and denominator times denominator.

Best ResponseYou've already chosen the best response.0Oh ok, Do you know how to do this one.... Solve \[4\sin ^{2}x+4\sqrt{2}cosx6=0\]
