Trigonometric equation identity, or whether an equation that is true, can be determined or verified by utilizing specific trig identities. Learn some basic identities, and how they apply in provided examples. Related to this Question Verify the following identity. cos (x - y) over sin x s...
Verifying the trigonometric identities means we have to show that the left-hand side of an equation is equal to the right-hand side, or vice versa. To do this, we will apply the basic trigonometry identities, represented below: cos2(x)+sin2(x)=11+tan2(x)=sec2(...
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
