If sinx=2cosx then, what is the value of sin2x?

Sin2x = 0.801

Step-by-step explanation:

Given  :  sinx = 2cosx .

To find : what is the value of sin2x.

Solution : We have given

sinx = 2cosx .

On dividing both sides by cos x

=  2 .

tan x = 2

Taking inverse of tanx .

x = .

x = 63.43

We need to find Sin2x .

Sin2x = Sin2(63.43)

Sin2x = Sin ( 126.86).

Sin2x = 0.801

Therefore, Sin2x = 0.801
