contains a list of sequential differences of sines of twenty-fourths of a right angle (increments of 3.75 degrees). This was the launching point for much of trigonometry for centuries to come.

The sides of right-angled triangles are labelled opposite, hypotenuse and adjacent. Trigonometry explores the relationship between sides and angles in right-angled triangles. The hypotenuse is the ...

With this curve I find out everything I need to know about that right triangle with just an angle and the length of the hypotenuse. Knowledge is power (as you will see). But where is the trig?

This is a completely different form of trigonometry that does not need the familiar modern concept of angles. At school we are told that the shape of a right-angled triangle depends upon the other ...

Classical trigonometry calls the separation between ... and one (representing lines at right angles). Associate Professor Wildberger says it would be possible to make a new protractor that ...

Trigonometric ratios of the angle- The ratios of the sides of a right triangle with respect to its acute angles are called trigonometric ratios of the angle. Consider a right triangle ABC ...

Two American high school students have stunned mathematicians after they claimed that they discovered a new way to prove Pythagoras' theorem by using trigonometry- a feat mathematicians thought ...

Our modern understanding of trigonometry harks back to ancient ... with just a measuring rope and unit rod make such accurate right angles? Well, by making a Pythagorean triple.
