The exponential constant eThe letter e is used in many mathematical calculations to stand for a particular number known as the exponential constant. This leaflet provides information about this important constant, and the related exponential function.
The exponential constant eThis leaflet gives some basic information about the constant e. It shows graphs of the exponential function. (Engineering Maths First Aid Kit 3.4)
The form Rcos(x-a)In this unit we explore how the sum of two trigonometric functions e.g.3 cos x plus 4 sin x, can be expressed as a single trigonometric function. Having the ability to do this enables us to solve trigonometric equations and find maximum and minimum values. (Mathtutor Video Tutorial)

Trig functions: cosecant, secant and cotangentIn this unit we see how the three trigonometric ratios cosecant, secant and cotangent can appear in trigonometric identities and in the solution of trigonometric equations. Graphs of the functions are obtained from a knowledge of sine, cosine and tangent. (Mathtutor Video Tutorial)

Trigonometric equationsThis workbook explains how a number of trigonometric equations can be solved by making reference to a Table of standard results and using the symmetries and periodicities present in the graphs of trig functions.
Trigonometric functionsThe sine, cosine and tangent of an angle are all defined in terms of
trigonometry, but they can also be expressed as functions. In this unit we
examine these functions and their graphs. We also see how to restrict the
domain of each function in order to define an inverse function.
