I think that you have gone too far. Simple substitution x'=x+1 will solve the problem in a few moments (clue: arctan(x)).
Good afternoon all,
I am looking at what I hope is my last trig substitution question:
Through completing the square I have:
My chosen substitution is:
and
Using this substitution I get:
For the new terminals of integration I get:
Subbing into the origanl integral:
from to
Resulting in:
Checking with my calculator shows that I should have come to:
My suspicion is that I mishandled the 1 in the denominator. Am I correct in this thinking?
