Implicit differentiation 2011-10-20 From Monica:Find dy/dx in terms of x and y, if sin(xy)=(x^2)-y.Answered by Penny Nom. differentiate y sin[x^2]=x sin[y^2] 2009-05-11 From mamiriri:derivate y sin[x^2]=x sin[y^2]Answered by Harley Weston. Implicit differentiation 2009-03-01 From Emily:determine the derivative y' at the point (1,0) y= ln(x^2+y^2) y'(1)= ??Answered by Stephen La Rocque. Implicit differentiation 2009-02-18 From Sunny:Find slope of the tangent line to the curve 2(x^2+y^2)2=25(x^2–y^2) at (3,-1)Answered by Robert Dawson and Harley Weston. Determine y'' by implicitly differentiating twice 2009-01-04 From Walter:Given x^3 - 3xy + y^3 = 1 , determine y'' by implicitly differentiating twice. I cannot solve this. Would you be kind enough to perform the mathematics and show the steps involved in obtaining the solution?Answered by Harley Weston. Trough Filling with Water 2008-08-21 From lanny:a triangular trough is 10 feet long, 6 feet across the top, and 3 feet deep. if water flows at the rate of 12 cubic inches per minute, find how fast the surface is rising when the water is 6 inches deep.Answered by Janice Cotcher.
