Solved Use implicit or logarithmic differentiation to find - Chegg

WebNov 30, 2016 · Explanation: differentiate implicitly with respect to x. Both terms on the left have to be differentiated using the product rule. ⇒ (xey. dy dx +ey.1) + (yex +ex. dy dx) = 0. ⇒ dy dx (xey +ex) = −ey − yex. ⇒ dy dx = − ey + yex xey + ex. Answer link. WebCalculus Derivative Calculator Step 1: Enter the function you want to find the derivative of in the editor. The Derivative Calculator supports solving first, second...., fourth derivatives, as well as implicit differentiation and finding the zeros/roots. You can also get a better visual and understanding of the function by using our graphing tool. Webcos²(xy)=x+y 2cos(xy) (-sin(xy)) (xdy + y dx) = dx + dy −2cos(xy) sin(xy) (xdy + y dx) = dx + dy ... So times the derivative of xy squared. So that's our left-hand side. We aren't done taking the derivative yet. And on our right-hand side, the derivative of x is just 1. And the derivative with respect to x of y is just going to be minus-- or ... city cafe kingfisher oklahoma
