Homework Statement
As part of a bigger problem, I am trying to find the area under the curve
f(x) = sqrt{2x - x2} between x = 0 and x = 2. To do this, I have to find the antiderivative of f(x)
Homework Equations
antiderivative
f(x) = axb
F(x) = a/(b+1) * xb+1
chain rule
f(x) = a(b(x))
f'(x) = b'(x) * a'(b(x))
The Attempt at a Solution
I took the derivative of the terms in the parenthesis, then what was outside the parenthesis, to get
2/3 * (x2 - x3/3)3/2
I don't think this is right, because you can use the chain rule to find the derivative, and it's not the original function.
NOTE- I'm not actually old enough and am not actual in a calculus course right now, but I figure that the homework forum would be the best place to put this. Also, don't give me answer, but rather gove me a direction to go in.
