int (e^(x))/((1+e^(x))(2+e^(x))) dx =...

`int (e^(x))/((1+e^(x))(2+e^(x))) dx =`

`log [(1 + e^(x))(2+e^(x))] + c`

`log [(1+e^(x))/(2+e^(x))] + c`

`log [(1+e^(x)) sqrt(2+e^(x))] + c`

इनमें से कोई नहीं

int (dx)/(1+x + x^(2) + x^(3))=
Text Solution
|
int (x-1)/((x-3)(x-2))dx=
Text Solution
|
int (1)/(cos x (1 + cos x))dx =
Text Solution
|
int (x)/((x-2)(x-1))dx का सही मान है (जहाँ p एक स्वेच्छ अचर है)
Text Solution
|
int (x^(2)+x - 1)/(x^(2) + x - 6) dx =
Text Solution
|
int (x^(2))/((x^(2) + 2) (x^(2)+3))dx =
Text Solution
|
int (dx)/((x^(2)+1)(x^(2)+4))=
Text Solution
|
int (1)/(x-x^(3))dx =
Text Solution
|
int (e^(x))/((1+e^(x))(2+e^(x))) dx =
Text Solution
|
int (dx)/(e^(x) + 1 -2e^(-x))=
Text Solution
|
int (x)/(x^(4) -1) dx =
Text Solution
|
int (dx)/(x(x+1))= जहाँ c स्वेच्छ अचर है
Text Solution
|
int (dx)/(sqrt(2x - x^(2))) =
Text Solution
|
int (x dx)/((x^(2)-a^(2))(x^(2)-b^(2)))=
Text Solution
|
int (1)/((x^(2)+a^(2))(x^(2)+b^(2)))dx =
Text Solution
|
यदि int (dx)/((x+2)(x^(2)+1))=a log |1 + x^(2)| + b tan^(-1) x + (1)/(...
