What is Trigonometry?
Trigonometry is all about understanding triangles. In its simplest forms, it
allows you to calculate lengths and angles in triangles. This is
FAR
more
important than your might first think and trigonometry is one of the most
obviously useful branches of mathematics. "Real-life" is full of examples and
jobs that are made much easier using trigonometric ideas and this has been
true for thousands of years.
For example: How do you think that the ancient Egyptians created
accurate right-angled corners for the pyramids? How would you
create an accurate right angle on a large scale?
