### Teach Yourself (14)

Applications of differentiation - maxima and minima

This unit explains how differentiation can be used to locate turning points.
It explains what is meant by a maximum turning point and a minimum turning point.

Differentiating sin(x) and cos(x) from first principles

After reading this text, and/or viewing the video tutorial on this topic,
you should be able to
differentiate the functions sin(x)and cos(x) from first principles.

Differentiation by taking logarithms

In this unit we look at how we can use
logarithms to simplify certain functions before we differentiate them.

Differentiation from first principles

After reading this text, and/or viewing
the video tutorial on this topic, you should be able to
understand the process involved in differentiating from first principles and
differentiate some simple functions from first principles.

Differentiation from first principles (powers of x)

This unit looks at some basic differentiation from first principles, and in particular how to differentiate powers of x.

Differentiation of the logarithm and exponential functions

In this unit the natural logarithm function and the exponential function are differentiated from first principles.

Extending the table of derivatives

This unit extends the basic table and produces a more complete and therefore more useful table.

Parametric differentiation

This unit explains how to differentiate a function defined parametrically.

Tangents and normals

This unit explains how to calculate the equation of the tangent and the normal to a curve at a given point.

The Chain Rule

This teach-yourself workbook explains the chain rule which is used to differentiate a function of a function.

Using a table of derivatives

This unit provides a basic table of some standard derivatives.
Many of the results are derived.

Implicit Differentiation

Sometimes functions are given not in the form y=f(x) but in a more complicated form in which it is difficult or impossible to express y explicitly in terms of x.. Such functions are called implicit functions. In this unit we explain how these can be differentiated using implicit differentiation. (Mathtutor Video Tutorial)

Introduction to differentiation 8.1 - Podcast

Maxima and Minima

In this unit we show how differentiation can be used to find the maximum and minimum values of a function. Because the derivative provides information about
the gradient or slope of the graph of a function we can use it to locate points on a
graph where the gradient is zero. We shall see that such points are often associated
with the largest or smallest values of the function, at least in their immediate
locality. In many applications, a scientist, engineer, or economist for example, will
be interested in such points for obvious reasons such as maximising power, or profit, or minimising losses or costs. (Mathtutor Video Tutorial)

Parametric differentiation

Instead of a function y(x) being defined explicitly in terms of the independent variable x, it is sometimes useful to
define both x and y in terms of a third variable, t say, known as a parameter. In this unit we explain how such
functions can be differentiated using a process known as parametric differentiation. (Mathtutor Video Tutorial)

Tangents and Normals

This unit explains how differentiation can be used to calculate the equations of the tangent and normal to a curve.
The tangent is a straight line which just touches the curve at a given point. The normal is a straight line which is
perpendicular to the tangent. (Mathtutor Video Tutorial)
