1 / | | 3 | 2 -x | x *E dx | / 0
Integral(x^2*E^(-x^3), (x, 0, 1))
Let .
Then let and substitute :
The integral of a constant times a function is the constant times the integral of the function:
The integral of the exponential function is itself.
So, the result is:
Now substitute back in:
Add the constant of integration:
The answer is:
/ | 3 | 3 -x | 2 -x e | x *E dx = C - ---- | 3 /
-1 1 e - - --- 3 3
=
-1 1 e - - --- 3 3
1/3 - exp(-1)/3
Use the examples entering the upper and lower limits of integration.
