Determine whether the integral converges.

i have some work, but i'm not sure it's correct. ?

You have one mistake which occurs when you integrate . The antiderivative of this is not in terms of . Instead, letting (or , if you want to bother with more signs) gives , making the indefinite integral equality



and then compute the definite integral from there.






Or, starting from the beginning, you could also have found it slightly more convenient to combine the substitutions in one fell swoop by letting . Then , and the integral becomes









Another way to do this is to notice that the integrand's denominator can be factorized.



So,



There are no discontinuities to worry about since you're integrate over , so you can proceed with integrating straightaway.








Just goes to show there's often more than one way to skin a cat...

The domain is 100 becuase i said so ok. jk its 00 jk again its r jk again and again its 75jk im always kiffing okaydbdbekufir83gc84vrudnmm as 8ehehenenrn vr 0eh339520252026ee6ee8e9
