Gradient and derivative

Gradient and derivative

Graph of a curve with an upward tangent labeled positive gradient, a horizontal tangent labeled stationary point, and a downward tangent labeled negative gradient

The gradient of a straight line is constant, but the gradient of a curve changes from point to point. To find the gradient at one exact point, we draw a tangent and measure the gradient of that tangent.
