Question

if theta=30 degre verify that
tan 2theta=2tan theta/1+tan square theta

Answer 1

$\large{\boxed{\underline{\purple{ANSWER\: :-}}}}$

Answer 2

Step-by-step explanation:

theta= 30°

2theta= 60°

as we know tan60°= √3

now the RHS

tan2theta= 2tan theta/ 1-tan^2theta

now putting the value

tan30°= 2 tan30°/1+tan^2 30°

=( 2/√3)/(1-1/3)

=√3
