# Part 5: The gradient at a point on a curve

In part 4, we saw how to find the derivative of any function of $$x$$ whose terms are of the form $$kx^n$$. To find the gradient at a particular point on the curve $$y=\text{f}(x)$$, we simply substitute the $$x$$-coordinate of that point into the derivative. Use this applet to see step-by=step examples and practise questions for yourself.
