Question

(A) We know that $5x = 3x + 2x$. Taking tangent on both sides,we get $	an 5x = 	an (3x + 2x)$. Using the formula $	an (A + B) = \frac{	an A + 	an

$	an 5x - 	an 3x - 	an 2x$

Vedclass · Answer

(A) We know that $5x = 3x + 2x$. Taking tangent on both sides,we get $	an 5x = 	an (3x + 2x)$. Using the formula $	an (A + B) = \frac{	an A + 	an B}{1 - 	an A 	an B}$,we have: $	an 5x = \frac{	an 3x + 	an 2x}{1 - 	an 3x 	an 2x}$. Cross-multiplying gives: $	an 5x (1 - 	an 3x 	an 2x) = 	an 3x + 	an 2x$. $	an 5x - 	an 5x 	an 3x 	an 2x = 	an 3x + 	an 2x$. Rearranging the terms,we get: $	an 5x 	an 3x 	an 2x = 	an 5x - 	an 3x - 	an 2x$.
