If sin x + cos x = 1, then the value of sin 2x is equal to

Answer»

Answer:

To find the value of SIN2X × Cos 2x, the trigonometric double angle formulas are USED. For the derivation, the values of sin 2x and cos 2x are used. So, Sin 2x Cos 2x = 2 Cos X (2 Sin x Cos2 x − Sin x)

Step-by-step explanation:

sin square x + cos square x + 2COS x sin x = 2sin x cos x. sin 2x = 0.
