A curve has equation x^2 +2xy–3y^2 +16=0. Find the coordinates of the points on the curve where dy/dx = 0.

x 2 +2xy–3y 2 +16=0Differentiate the terms:x 2 gives 2x2xy is differentiated by the product rule: vu' +v'u Make v = 2x and u = y, which gives 2x(dy/dx) + 2y3y 2 gives 6y(dy/dx)16 gives 0.Therefore we have th...
