Calculus 1 Lecture Notes, Section 2.8

Proof: Since r is rational, that means for integers p and q. Let . Then . Using implicit differentiation: Derivatives of the Inverse Trigonometric Functions, for –1 < x < 1. Proof: iff sin y = x, for –1 < x < 1. Proof: iff cos y = x. Proof: iff tan y = x, for |x| > 1. Proof: iff sec y = x. Proof: iff cot y = x, for |x| > 1. Proof… ................
