How do you prove sin^2x + cos^2x = 1? + Example - Socratic.org

1. Maximum value of cos 2 ( x) = 1. Minimum value of sin 2 ( x) = 0. So this is the only case where you get cos 2 ( x) − sin 2 ( x) = 1. Hence cos 2 ( x) = 1 and sin 2 ( x) = 0 => x = n π. Or you coul

No you may not. If you'd like to divide by 2, you must divide both terms on the LHS by 2. Not just your 2cos(2x) term. If you divided both terms by two, you'd be left with cos(2x)+ 21 sin(x) = 41 ...
