Integral(-1/10*1/E^x, (x, 2/5, 11/5))
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 is when :
Now substitute back in:
So, the result is:
Add the constant of integration:
The answer is:
/ | -x | 1 e | -1/10*--*1 dx = C + --- | x 10 | e | /
-2/5 -11/5
e e
- ----- + ------
10 10
=
-2/5 -11/5
e e
- ----- + ------
10 10
