Answer: Double table lookup The following integrals may

Problem 70E

Double table lookup The following integrals may require more than one table lookup. Evaluate the integrals using a table of integrals, then check your answer with a computer algebra system. When the parameter a appears, assume a > 0.

               dx.

Answer;

Step 1

                  The given integral is   dx , and a> 0………(1)

 Now , we have to evaluate  the given integral  by using table of integrals.

                    Now ,   the integrand can be written as;

                   =

                                     =  )

                                    = ………….(2)

From(1) , and (2) ; the given integral can be written as ;

             dx  =  dx………..(3)
