18.find int ln(x+sqrt(x^(2)+a^(2)))

int log(x+sqrt(x^(2)+a^(2)))dx

int log (x+sqrt(x^(2)+a^(2)))dx =

" (1) "int log(x+sqrt(x^(2)-a^(2)))dx

Evaluate the following: int log (x + sqrt (x^2 +a^2) ) dx

Integrate : int x log(x+sqrt(x^(2)+a^(2)))dx

Integrate : int log(x+sqrt(x^(2)+a^(2)))dx

Integrate : int log(x+sqrt(x^(2)-a^(2)))dx

Using the result int(dx)/(sqrt(x^(2)+a^(2)))=log|xsqrt(x^(2)+a^(2))|+C , Evaluate int(-"cosec"^(2)xdx)/(sqrt(cot^(2)x+9))

the value of int x*(ln(x+sqrt(1+x^(2))))/(sqrt(1+x^(2)))dx
