Solutions

Chapter 3.3, Problem 1E
To determine

Find the differentiate form of the given function.

Expert Solution

Answer to Problem 1E

The differentiate form of the given function is f'(x)=6x+2sinx .

Explanation of Solution

Given:

The given function is f(x)=3x22cosx .

Calculation:

Use power rule and derivative of the trigonometric function.

  ddx(xn)=nxn1,n>0 and ddx(cosx)=sinx

  f(x)=3x22cosxddxf(x)=ddx(3x2)ddx(2cosx)f'(x)=6x2(sinx)f'(x)=6x+2sinx

Hence the differentiate form of the given function is f'(x)=6x+2sinx .
