sin(x y) = sin x cos y cos x sin y Solve for ? cos (theta)=- (square root of 2)/2 cos (θ) = − √2 2 cos (θ) = - 2 2 Take the inverse cosine of both sides of the equation to extract θ θ from inside the cosine. θ = arccos(− √2 2) θ = arccos (- 2 2) This is a well used trig. relation along with sin(π 2 −θ) that is : cos(π 2 − θ) = sinθ and sin(π 2 −θ) = cosθ Basically sin (angle) = cos (complement) and cos (angle) = sin (complement) Notice how a "co- (something)" trig ratio is always the reciprocal of some "non-co" ratio. You can use this fact to help you keep straight that cosecant goes with sine and secant goes with cosine. The following (particularly the first of the three below) are called "Pythagorean" identities.
