Definite Integral

₀âˆ«^âˆž dx / (x²+a²)(x²+b²)

do we need to apply partial fraction here ??

hey its not partial derivative it is partial fraction.

oops..ya..made d change

yup! u hve to do that..

should i show u the steps????

actually this is that type of ques where u hve to follow indefinite integral steps and then execute the limits...

u would get

1=A(x²+b²)+B(x²+a²)

solve to get

A=1/(b²-a²) and B = -1/(b²-a²)

put dese and u will get the answer as
\pi /4ab(a+b)

do tell if u want a detailed answer..

ok..thanks..

guess there's no way to use DI properties then..
