Thread: gradient

find the gradient to the curve y = x^3 - 3x^2 at the point x = 3
then find the equations of the tangent and the normal to the curve at the point where x = 3


thanks

So the slope of your tangent is , and the slope of your normal is .

Also, since
,
both equations will pass through the point .
