Verified by Experts

The correct Answer is:

C

int(1)^(2)(1)/(x^(2))e^(1/x)*dx=
Text Solution
|
If I(1)=int(e)^(e^(2))(dx)/(ln x) and I(2)=int(1)^(2)(e^(x))/(x)dx
Text Solution
|
int1^2(1/x-1/(x^2))e^x dx=e(e/2-1)
Text Solution
|
If A=int(0)^(1)(e^(x))/(x+1)dx then int(0)^(1)(x^(2)e^(x))/(x+1)dx=
Text Solution
|
int- 1^1(e^(-1/ x))/(x^2(1+e^(-2/ x)))dx is equal to :
Text Solution
|
int(1)^(e^(2))(dx)/(x(1+log x)^(2))=
Text Solution
|
int(1)^(2)(e^(1//x))/(x^(2))dx
Text Solution
|
int(1)^(2) ((x-1)/(x^(2)))e^(x) dx
Text Solution
|
int(1)^(2)((x-1)/(x^(2)))e^(x)dx.
