Derivative of sin^5 x [by Chain Rule] | sin^5x Derivative

The derivative of sin5x is equal to 5sin4x cosx. In this post, we will learn how to differentiate sin5x, that is, sine to the power 5 of x.

Derivative of sin^5 x

Derivative of sin5x Formula:

The derivative of sin5x is denoted by ddx(sin5x) or (sin5x). The formula of the derivative of sin5x is given below:

ddx(sin5x)=5sin4xcosx, or (sin5x)=5sin4x cosx.

Derivative of sin^5x

Answer: The Derivative of sin5x is 5sin4x cosx.

Proof:

Step 1: Let us assume that z=sin x. Then we can write our function as

sin5x=z5

Step 2: Note that dzdx=cosx as z=sinx.

Step 3: By the chain rule, the derivative of sin5x will be equal to

ddx(sin5x)=ddz(z5)dzdx

=5z4(cosx) by the power rule of derivatives: ddx(xn)=nxn1

=5sin4xcosx as z=sinx

=5sin4xcosx.

Conclusion: The derivative of sin5x is 5sin4x cosx and this is obtained by the chain rule and the power rule of derivatives.

In a similar way, one can obtain the derivative of sinn x, which is given below:

ddx(sinnx)=nsinn1xcosx.

For example,

  1. The derivative of sin2x is 2sin x cos x.
  2. The derivative of sin3x is 3sin2 x cos x.
  3. The derivative of sin4x is 4sin3 x cos x.
