how would one evaluate this without using trig substitution? Is it possible to make one integral out of this?(adsbygoogle = window.adsbygoogle || []).push({});

{int[(y^2 + a1^2)^-1]dy +c1}/{int[(x^2 + a2^2)^-1]dx +c2} +c3

the numbers behind the 'a's and 'c's are supposed to be subscripts.

Also, how would one deal with this:

{int[(y^2 + a1^2)^-1]dy +c1}/(a tan{int[(x^2 + a2^2)^-1]dx +c2}) +c3

Please advise
