Question

Find the value of 8sin 2xcos 4xsin 6x,when x=15​

Answer 1

Answer:

value of 8sin2x cos4x sin6x is 2

Step-by-step explanation:

Given :- x = 15

Find :- 8sin2x cos4x sin6x

___________________________

Solution:- 8sin2*(15°) cos4*(15°) sin 6*(15°)

=> 8sin30° cos60° sin90°

We know that , sin30° = 1/2

cos60° = 1/2

sin90° = 1

∴ 8 * 1/2 * 1/2*1

=> 8*1/4

=> 2 Answer
