Question

`intx^2 e^(x^3) dx` equals: 

Options

  • `1/3  e^(x^3) + C` 

  • `1/3  e^(x^2) + C` 

  • `1/2  e^(x^3) + C`

Solution

`1/3  e^(x^3) + C` 

स्पष्टीकरण:

`int x^2 e^(x^3)` dx

Putting x3 = t, 3x2 dx = dt

`= 1/3 int (3x^2)e^(x^3)` dx

`= 1/3 int e^t  dt = 1/3  e^t + C`

`= 1/3  e^(x^3) + C`
