WebMar 24, 2024 · To reduce it to one variable, use the fact that x(t) = sint and y(t) = cost. We obtain dz dt = 8xcost − 6ysint = 8(sint)cost − 6(cost)sint = 2sintcost. This derivative can also be calculated by first substituting x(t) and y(t) into f(x, y), then differentiating with respect to t: z = f(x, y) = f (x(t), y(t)) = 4(x(t))2 + 3(y(t))2 = 4sin2t + 3cos2t.
