Use the Table of Integrals on Reference Pages 6‒10 to evaluate the integral.

25. 4 + ( ln x ) 2 x d x

To determine

To evaluate: The integral function 4+(lnx)2xdx.

Explanation of Solution

Given information:

The integral function is 4+(lnx)2xdx.

Calculation:

Express the integral function as shown below:

4+(lnx)2xdx (1)

Consider u=lnx (2)

Differentiate both sides of Equation (2).

du=dxx

Substitute u for lnx and du for dxx in Equation (1).

4+(lnx)2xdx=22+u2du (3)

Show the integral formula from table of integrals as follows:

a2+u2du=u2a2+u2+a22ln(u+a2+u2)+C

Apply the integral formula in Equation (3).

4+(lnx)2xdx=22+u2du=u222+u2+222ln(u+22+u2)+C=u24+u2+2ln(u+4+u2)+C (4)

Substitute u for lnx in Equation (4)
