Sin / Cos / Tan
Sin/Cos/Tan is a very basic
form of trigonometry that
allows you to find the lengths
and angles of right-angled
triangles. A very easy way to
remember the three rules is
to to use the abbreviation
SOH CAH TOA...

Coordinate Geometry
Coordinate Geometry
involves using functions and

geometry we cannot only find
the equations of lines but we
can also do a lot of
interesting and useful...

Sine Rule
Sine rule is another
trigonometry rule that allows
you to find missing angles
and sides of certain triangles
(in some cases you will have
to use cosine rule). On the
right, you can see the two
different types of sine rule...

Angles
An angle is the amount by
which a line turns. Every two
lines that meet at one of their
ends have an angle. Angles
are measured in degrees (°)
and range from 0 (no
rotations) - 360 (full rotation).
There are a lot of shape...
