int(dx)/((x^2-1)sqrt(x^2+1))=

Answer»

`(1)/(2sqrt(2))log|(SQRT(1+X^2)+sqrt(2)x)/(sqrt(1+x^2)-sqrt(2)x)|+c`
`(1)/(2sqrt(2))log|(sqrt(1+x^2)+sqrt(2))/(sqrt(1+x^2)-sqrt(2))|+c`
`(1)/(2sqrt(2))log|(-sqrt(1+x^2)+sqrt(2)x)/(sqrt(1+x^2)+sqrt(2)x)|+c`
`(1)/(2sqrt(2))log|(sqrt(1+x^2)-sqrt(2)x)/(sqrt(1+x^2)+sqrt(2)x)|+c`
