Chapter 19 Proportions and graphs

# 19.5 Non-linear Graphs

A nonlinear function is a function whose graph is not a straight line. The tangent to a curved graph is a straight line that touches the graph at a point. The gradient at a point on a curve is the gradient of the tangent at that point. In this section, we learn about Introduce the concept of tangent to a curve at a particular point, Discuss using an interactivity the tangent to a curve at a particular point, Find a gradient to a curve at a particular point, tangents.

If you're a student in a school/college that's based in England, you might be entitled for full access to our eLearning platform where you can access to all our tutorial videos and practice questions.

Please check with the head of Maths or deputy headteacher at your school/college to request access if they've already registered to our free pilot subscription. They can always reach us at the below email:
