conclude that since the integral of sin(x) equals -cos(x), the integral of sin^2(x) should equal -cos^2(x); in fact, the answer does not contain a cosine at all. You cannot directly integrate sin^2(x). Use trigonometric identities and calculus substitution rules to solve the ...

that make the equation true. For example, the equation sin x + 1 = cos x has the solution x = 0 degrees because sin x = 0 and cos x = 1. Use trig identities to rewrite the equation so that there's only one trig operator, then solve for the variable using inverse trig operators...
