Question

Tan 8 theta - tan 5 theta -tan3 theta = tan8 theata ×tan 5 theta × tan3 theata

Answer 1

Step-by-step explanation:

tan 8 theta = tan 5 + 3 theta

= tan (5+3)theta

tan 8 theta = tan 5 theta + tan 3 theta/ 1- tan 5 theta.tan 3 theta

Tan 8 theta (1-tan 5 theta.tan 3 theta )=tan 5 theta+ tan 3 theta

Tan 8 theta - tan 8 theta.tan 5 theta .tan 3 theta = tan 5 theta + tan 3 theta

Tan 8 theta - Tan 5 theta - Tan 3 theta = Tan 8 theta.Tan 5 theta.Tan3 theta

is proved
