Integral(x^2*x/E^3, (x, 0, 1))
The integral of a constant times a function is the constant times the integral of the function:
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 is when :
So, the result is:
Now substitute back in:
So, the result is:
Add the constant of integration:
The answer is:
/ | | 2 4 -3 | x *x x *e | ---- dx = C + ------ | 3 4 | e | /
