TRIGONOMETRY

Trigonometry as the name implies, involves the study or measurement of triangles in relation to their sides and angles. It is interesting to note that trigonometry has a very significant relevance in real life hunting, traveling and is well applied in the field of sciences, engineering, navigation of ships, aero planes and astronomy.


STUDY UNITS
There are seven study units in this course
Units 1 and 2 Trigonometric ratios I and II
Units 3 -Inverse of trigonometric ratios
Units 4 -Graph of trigonometric ratios
Units 5 Trigonometric Identities and trigonometric equations
Unit 6
Solution of triangle (sine and cosine values) and Angles
of elevation and depression.
Unit 7 Bearings.
The first four units concentrate on trigonometric ratios and terms inverse
trigonometric functions and graphs, next on trigonometric identities and
equations, while the last two units disussing the applications of trigonometric
ratios to real life problems.
Each study unit consists of two to three weeks works at the rate of three hours
per week. It includes specific objectives direction of study recommended
textbooks, summary of the unit and conclusion. At the end of each unit there
is an exercise to enable you assess yourself on how far you have understood
the contents of the unit and have achieved the stated objectives in the
individual units in the course in general.
