A curve is defined by the parametric equations x = 2t and y = 4t^2 + t. Find the gradient of the curve when t = 4

the gradient of the curve = dy/dx and dy/dx = (dy/dt)(dt/dx) dy/dt = 8t + 1 dx/dt = 2 therefore dt/dx = 1/2 dy/dx as above = (8t + 1) * 1/2 = (8t + 1)/2 where t = 4, dy/dx = (8*4 + 1)/2 = (32 + 1)/2 = 33/2
