Evaluate the integral by making the given substitution. (use c for the constant of integration.) sec2(1/x9) x10 dx, u = 1/x9

Step-by-step explanation:

The question requires addition information. Below is how the question should be rightly stated.

          ------(1)

Using substitution method,

We are given                   -------(2)

                      ⇒

Differentiating u with respect to x,

Making dx the subject of the equation

                                              ---------(3)

Substituting the values of u from equation (2) and dx from equation (3) into equation (1)

substituting the value of u
