" (a) "quad log(x+sqrt(1+x^(2)))

The function f(x)=sin ( log (x+ sqrt(1+x^(2)))) is

If f(x) = ln (x - sqrt(1 + x^(2))) , then what is int f''(x) dx equal to ?

If y sqrt(1+ x ^(2)) = log ( x + sqrt( 1 + x ^(2))) then (1 + x ^(2)) y_(1) + xy=

int ln(x+sqrt(1+x^(2)))dx

The value of int_(-1)^(1) (log(x+sqrt(1+x^(2))))/(x+log(x+sqrt(1+x^(2))))f(x) dx-int_(-1)^(1) (log(x +sqrt(1+x^(2))))/(x+log(x+sqrt(1+x^(2))))f(-x)dx ,

The function f(x) = sec[log(x + sqrt(1+x^2))] is

The function f(x) = sec[log(x + sqrt(1+x^2))] is

The function f(x) = sec[log(x + sqrt(1+x^2))] is

The function f(x) = sec[log(x + sqrt(1+x^2))] is

The value of int_(-1)^(1) ((logx+sqrt(1+x^(2))))/(x+log(x+sqrt(1+x^(2))))f(x) dx-int_(-1)^(1) (log(x sqrt(1+x^(2))))/(x+log(x+logsqrt(1+x^(2))))f(-x)dx ,
