# What Is the Derivative of Cos3x?

August 26, 2022

The derivative of cos3x is equal to -3 sin3x. The derivative of a function gives the rate of change of that function with respect to the change in the variable.

## What is the nth derivative of cos3x?

cos3x + 3. cosx/4), Ans.

## 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.

## 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?

Sin 3x = Sin (2x + x)

## What is the derivative of sinx?

The derivative of sin x is denoted by d/dx (sin x) = cos x. The other way to represent the sine function is (sin x)’ = cos x.

## What is the derivative of 2sin2x?

Since 2 is constant with respect to x, the derivative of 2sin(2x) 2 sin ( 2 x ) with respect to x is 2ddx[sin(2x)] 2 d d x [ sin ( 2 x ) ] .

## What is cos 3a?

Antworten. Also cos3A= −3cosA+4cos3A.

## What is the range of cos3x?

Trigonometry examples

The range is −1≤y≤1 – 1 ≤ y ≤ 1 .
