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