### Introducing Derivatives

Differentiation allows to find rates of change. The derivative is the rate at which one quantity changes with respect to an other. When we differentiate a function we find the gradient function. On a graph, the derivative is the slope of...

### Graphs and Derivatives

On the following page, we will look at graphs and derivatives. We will get some practice in sketching gradient functions and we will carefully consider stationary points (maximum, minimum and points of inflexion) as well as non-stationary points of inflexi

### Chain Rule

The Chain Rule is used for differentiating composite functions. The rule itself looks really quite simple (and it is not too difficult to use). The most important thing to understand is when to use it and then get lots of practice. It is...

### Product and Quotient Rule

The Product Rule is a formula that we can use to differentiate the product of 2 (or more) functions. The Quotient Rule is for the quotient of two functions (one function divided by another). The rules are quite easy to apply. The challenge...

### Equation of Tangent and Normal

On this page we look at how to find the equation of a tangent and also the normal to a curve. A tangent is a straight line that touches a curve at one point and has the same gradient as the curve at that point. A normal is straight line...

### Implicit Differentiation

This page is all about implicit equations and how we find the gradient of them. Implicit equations are equations which are not written explicitly – I’ll explain later! Examination questions typically ask you to find the equation of a...

### Mixed Differentiation

This page is ideal for practising all the skills of differentiation. There are a series of quizzes that you can work through. You may wish to use this page in preparation in preparation for a test on this topic or the final or practice examinations.

### Definite Integration

Integration is sometimes called antidifferentiation, as it is the opposite process of differentiation. When we find an indefinite integral we find a function with an abritrary constant, C. When we find a definite integral, we find a numerical value.

### Area between Graphs

On this page, we'll look at how we can use integration to find areas. This is a really common question in examinations. The technique is not too hard, but there are just a couple of pitfalls to avoid which will be explained. There are...

### Integration by Substitution

Integration by substitution or U-substitution is a method that will help you integrate many different functions. By changing the variable of the integrand, we can make an apparently difficult problem into a much simpler one. The challenge is recognising wh

### Integration by Parts

Integration by parts is a method of integration that we use to integrate the product (usually !) of two functions. The aim is to change this product into another one that is easier to integrate. Although the formula looks quite odd at first glance, the tec
