Ap Calculus Ab Question

Test Preparation

<p>Hello, I have a couple questions here that I’m not too sure on, and I was wanting to know if anyone out there could be of some assistance.</p>

<li><p>Write the definite integral that represents the area of the region
enclosed by y=4x-x^2 and the x-axis.</p></li>
<li><p>Write the definite integral for the area of the region lying in the upper half
of the elipse given by 4x^2 + y^2 = 4</p></li>
</ol>

<p>thanks,</p>

<p>Anyone out there know how to do these ?</p>

3

<p>These problems are very basic. Just find the bounds by setting y=0 and integrate.</p>

4

<p>so number 1 would be 0 to 4 (2x^2-X^3/3)</p>

<p>what would the 2nd one be since its upper half.</p>

5

<p>nevermind, you wouldn't have to integrate it. it stays the same.</p>
