Webtan 2A = 2 t a n ( A 2) 1 – t a n 2 ( A 2) Example : Find the value of Tan 120 Degrees ? Solution : We Know that tan 60 = 3. By using above formula, tan 2A = 2 t a n A 1 – t a n 2 A. tan 120 = 2 t a n 60 1 – t a n 2 60 = 2 × 3 1 – 3. tan 120 = − 3. WebFor the next trigonometric identities we start with Pythagoras' Theorem: The Pythagorean Theorem says that, in a right triangle, the square of a plus the square of b is equal to the square of c: a 2 + b 2 = c 2. Dividing through by c2 gives. a2 c2 + b2 c2 = c2 c2. This can be simplified to: ( a c )2 + ( b c )2 = 1. david kalac posts
