A curve is defined by parametric equations: x = t^(2) + 2, and y = t(4-t^(2)). Find dy/dx in terms of t, hence, define the gradient of the curve at the point where t = 2.

dy/dx = (dy/dt)/(dx/dt) y = t(4-t 2 ), then using differentiation of y with respect to t, dy/dt = 4 - 3t 2 x = t 2 + 2, then using differentiation of x with respect to t, dx/dt = 2t Find dy/dx by dividing dy...
