1 / | | 2 | 4*x | x*E dx | / 0
Integral(x*E^(4*x^2), (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:
/ | 2 | 2 4*x | 4*x e | x*E dx = C + ----- | 8 /
4 1 e - - + -- 8 8
=
4 1 e - - + -- 8 8
-1/8 + exp(4)/8
Use the examples entering the upper and lower limits of integration.
