How do you find the derivative of y cos3x?

What is the derivative of sin3x?

The derivative of sin3x is equal to 3cos3x.

What is the derivative of cos2x?

Solution: The derivative of cos 2x is -2 sin 2x.

How do you draw cos3x?

Is Cos 3x COSX 3?

No, cos(x)^3 means the cos of the angle is triple or multiplied by itself 3 times. If x = 2, then x^3 = 8. This is called exponentiation.

What is the derivative of cos?

The derivative of the cosine function is written as (cos x)’ = -sin x, that is, the derivative of cos x is -sin x.

What’s the derivative of sin2x?

The derivative of sin 2x is 2 cos 2x. We write this mathematically as d/dx (sin 2x) = 2 cos 2x (or) (sin 2x)’ = 2 cos 2x.

What is sin3x formula?
