Maths - Basic angles, distances and coordinates

A brief introduction to this section.

The basic principle of Pythagoras theorem and some simple examples with numbers in.

Convert decimal degrees into the 'degrees, minutes and seconds' format, add angles together and subtract angles from each other without using a calculator.

A worked example with each step explained.

A brief introduction to the section.

A very basic explanation of what is meant by 'degrees, minutes and seconds'.

A brief introduction to the section.

In this lecture you will learn how to use the basic trigonometry formulas and go through some simple examples with numbers in.

A brief introduction to the section.

A basic explanation of the principle of coordinates, how they work, what they are used for and instructions on how to plot coordinates indicatively on a diagram.

A worked example of how to calculate the distance between two points of which you know the coordinates.

A brief introduction to the section.

How to identify the whole circle bearing between two points and how to calculate the back bearing when you know the forward bearing.

A worked example for the scenario where the WCB is in quadrant 1 (between 0 and 90 degrees, with 0 degrees being vertically upwards).

A worked example for the scenario where the WCB is in quadrant 2 (between 90 and 180 degrees, with 0 degrees being vertically upwards).

A worked example for the scenario where the WCB is in quadrant 3 (between 180 and 270 degrees, with 0 degrees being vertically upwards).

A worked example for the scenario where the WCB is in quadrant 4 (between 270 and 360 degrees, with 0 degrees being vertically upwards).

Test yourself on what you've learnt. There are some basic questions and some which require you to extrapolate what you've learnt.
