WebbThe fact that you can take the argument's "minus" sign outside (for sine and tangent) or eliminate it entirely (for cosine) can be helpful when working with complicated expressions. Angle-Sum and -Difference Identities sin (α + β) = sin (α) cos (β) + cos (α) sin (β) sin (α − β) = sin (α) cos (β) − cos (α) sin (β) Webbcosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ … WebbCosine is a cofunction of sine A cofunction is a function in which f (A) = g (B) given that A and B are complementary angles. In the context of cosine and sine, cos (θ) = sin (90° - θ) sin (θ) = cos (90° - θ) Example: cos (30°) = sin (90° - 30°) = sin (60°) hill 492
