Question

2sinthetacostheta is equals to what

Answer 1

Answer:

$2sin\theta cos\theta\\=sin\:2\theta$

Step-by-step explanation:

$2sin\theta cos\theta\\=sin\:2\theta$

__________________________

Since ,

We know the formula :

sin(A+B) = sinAcosB+cosAsinB

Here,

Sin 2A

=sin(A+A)

= sinAcosA+cosAsinA

= sinAcosA+sinAcosA

= 2sinAcosA
