Question

state and prove double angle theorem can u keep photo by solving ​

Answer 1

Step-by-step explanation:

The double angle formulae for sin 2A, cos 2A and tan 2A

and this is our second double angle formula. Similarly tan(A + A) = tan A + tan A 1 − tanA tanA so that tan 2A = 2 tanA 1 − tan2 A These three double angle formulae should be learnt

Answer 2

$\fbox\red{A}\fbox\blue{N}\fbox\red{S}\fbox\blue{W}\fbox\red{E}\fbox\blue {R}$

The double formula for sin 2A,

cos 2A and tan 2A

and this is our second double angle formula. similarly tan (A + A) = tan A + tan

A 1 – tanA so that tan 2A = 2 tanA 1 – tan2 A. These three double angle.
