WebSo, the formula tells us that arc length of a parametric curve, arc length is equal to the integral from our starting point of our parameter, T equals A to our ending point of our parameter, T equals B of the square root of the derivative of X with respect to T squared plus the derivative of Y with respect to T squared DT, DT.
WebSo let's just rewrite our function here, and let's rewrite it in terms of x. So if y is equal to 15 over x, that means if we multiply both sides by x, xy is equal to 15. And if we divide both sides by y, we get x is equal to 15 over y. These right over here are all going to be equivalent. Now how does this right over help you? hereof vs heretoWebX Power.
