Find the average value of the function f(x)=xe^(-x^2).
Solution
You have to know what the interval is to determine the average value.
Once you have it the formula is int f(x) from x=a to x=b divided by (b-a).
So here the antiderivative is -1/2 e^(-x^2)
So from a to b the average value is (1/2ea^2 -1/2 e^b^2)/(b-a)
