Sin * Cos == ?????....

1.	Sin * Cos == ?????....
Answer» ong>Explanation: Sin × Cos = 1 sin(A + B) = sin(A)cos(B) + cos(A)sin(B) Now LET A = B = x. So we get: sin(x + x) = sin(2X) = sin(x)cos(x) + cos(x)sin(x) = 2sin(x)cos(x) THEREFORE, sin(x)cos(x) = (1/2)sin(2x) Hope this helps!

ong>Explanation:

Sin × Cos = 1

sin(A + B) = sin(A)cos(B) + cos(A)sin(B)

Now LET A = B = x. So we get:

sin(x + x) = sin(2X) = sin(x)cos(x) + cos(x)sin(x) = 2sin(x)cos(x)

sin(x)cos(x) = (1/2)sin(2x)

Hope this helps!
