`intsqrt((x-1)/(x+1))dx` is equal toA. `2sqrt(x^(2)+1)+sin^(-1)x+C`B. `sqrt(x^(2)-1)-sin^(-1)x+C`C. `sqrt(x^(2)-1)+sin^(-1)x+C`D. `(sqrt(x^(2)-1))/(2)+sin^(-1)x+C` |

Answer» Correct Answer - B Let `l=intsqrt((x-1)/(x+1))dx` `rArr" "l=int(x-1)/(sqrt(x^(2)-1))dx=int(x)/(sqrt(x^(2)-1))dx-int(1)/(sqrt(x^(2)-1))dx` `=sqrt(x^(2)-1)-sin^(-1)x+C` |
