PROBLEM
Find an antiderivative of f(x)=x2−10ex.
STEP 1
Assumptions1. The function is f(x)=x−10ex
. We are looking for an antiderivative of the function, which means we want to find a function F(x) such that F'(x) = f(x)
STEP 2
The antiderivative of a function is found by integrating the function. So we need to integrate f(x).
∫f(x)dx=∫(x2−10ex)dx
STEP 3
We can split the integral into two separate integrals because of the subtraction operation in the function.
∫(x2−10ex)dx=∫x2dx−∫10exdx
STEP 4
Now, we can integrate each part separately. The integral of x1 is ln∣x∣, and the integral of ex is ex.∫x2dx−∫10exdx=2∫x1dx−10∫exdx
STEP 5
Now, integrate each part.
2∫x1dx−10∫exdx=2ln∣x∣−10ex
SOLUTION
Finally, we add the constant of integration, C, to the result. This is because the antiderivative is not unique and can differ by a constant.
2ln∣x∣−10ex+CSo, an antiderivative of the function f(x)=x2−10ex is (x)=2ln∣x∣−10ex+C.
