What are the Quotient Identities or Tangent Identities?
\(\tan \theta = \frac{{\sin \theta }}{{\cos \theta }},\cot \theta = \frac{{\cos \theta }}{{\sin \theta }}\)

What are the Pythagorean Identities?
\({\sin ^2}\theta + {\cos ^2}\theta = 1,{\tan ^2}\theta + 1 = {\sec ^2}\theta ,1 + co{t^2}\theta = {\csc ^2}\theta \)
