Step-by-step explanation:

Answer 2

Answer:

No

Step-by-step explanation:

They are not same. 2 sinA means multiplying the value of sinA by 2 and sin 2A means multiplying angle A by 2 . For example -

let A = 30 degree.

So, 2 sin A= 2* sin 30 = 2* 1/2= 1.

(* means multiply )

sin2A = sin(2*30)

= sin 60
