In this video I show you how to evaluate the six trigonometric functions given a point. We will evaluate, sine, cosine, tangent, cosecant, secant, and cotangent. Yes, I am wearing a shirt with my face ...

I am in charge of a science-track class for second-year high school students.We have currently started studying Mathematics ...

A worksheet on derivatives of sine, cosine, tangent, cotangent, secant and cosecant and the chain rule. Detailed solutions are included. A bundle is a package of resources grouped together to teach a ...

Mathematics students have cause to celebrate. A University of New South Wales academic, Dr Norman Wildberger, has rewritten the arcane rules of trigonometry and eliminated sines, cosines and tangents ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Learn about graphs of trigonometric functions in this National 5 Maths guide.

Excel has built-in functions for sine and cosine, the two core trigonometric functions, and for hyperbolic sine and hyperbolic cosine, their hyperbolic counterparts. It also has built-in functions for ...

A worksheet on differentiating functions involving sine, cosine, tangent, cotangent, secant and cosecant. The exercises require the use of the basic rules: rule for constant functions, power rule, ...

The Pythagorean Theorem—discovered by the Greek mathematician Pythagoras in the 6th century BCE—is a cornerstone of mathematics. Simply stated as a 2 + b 2 = c 2, the theorem posits that the sum of ...

In 2022, two high school students created a trigonometric proof of the Pythagorean Theorem—something that’s only ever been accomplished by a few professional mathematicians. Now, a new article not ...
