Evaluate the integral by making the given substitution. (use c for the constant of integration.) sec2(1/x7) x8 dx, u = 1/x7

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

                     

 

I cant remember exactly but i do remember having to do this question and quizlet had the awnser

Step-by-step explanation:

Answer is    ======i assume this is what this is what question asks for as it makes the substitution work:     if      then by simple differentiation, we have    note that    therefore, performing these substitutions:    

Here is a solution :
