<p>I direly need help with my ap Calc homework. Can anyone help?</p>

<p>Consider the curve y^2 = 4 + x and the chord AB joining the points A(-4, 0) and B(0,2) on the curve.</p>

<p>(a) Find the x- and y-coordinates of the point on the curve where the tangent line is parallel to chord AB.</p>

<p>(b) Find the area of the region R enclosed by teh curve and the chord AB.</p>

<p>(c) find teh volume of the solid generated when the region R, defined in part (b), is revolved about the x-axis.</p>

<p>guys, I've never been good at circles, so if anyone can help I'd really really appreciate it! I'm like getting a deficiency in AP calc, so please I'd appreciate any help!</p>

<p>Thanks</p>

<p>duuuude, two calculus problems today that are easily solveable...i am so lazy. im serious. for the first one do dy/dx and then stick in the slope for dy/dx and then solve for the point that the slopes are equal.</p>

<p>then using the formula for a line, get the formula for the chord, then do the integral of the function minus the chord on the interval where the function is greater than the chord.</p>

<p>then use circular cross sections to do the volume around the x-axis</p>

<p>lol i'm such a bone head
thank you!</p>

<p>For next time, it's usually easy to see something like that if you draw yourself a diagram.</p>
