How to Use Trig Functions in Excel. Excel has built-in functions for sine and cosine, the two core trigonometric functions, and for hyperbolic sine and hyperbolic cosine, their hyperbolic ...

Alex Tabarrok points to a new paper this morning that should thrill data nerds and chart enthusiasts everywhere. Steven Piantadosi of the University of Rochester has produced a simple equation ...

Use as an introduction or recap to lessons on trigonometry. Discuss with students that the different trig functions are based on ratios and show this by comparing similar triangles.

A unit circle is an important part of trigonometry and can define right angle relationships known as sine, cosine and tangent.

The mathematical study of triangles has just got a whole lot simpler, according to a researcher who says his new theory of trigonometry is easier to use and more accurate. Associate Professor ...

The booklet discusses slide rule operation, use of certain special scales, applications of trigonometry, and the principles underlying slide rules. Hartung focused on the operations of the instrument ...

Of course, plenty of proofs of this theorem exist, but very few use trigonometry to make their argument—the theorem is so central to that particular field of mathematics that to do so would ...

In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using trigonometry, including a proof they discovered in high school.
