Often neglected as ‘merely a styling language’, CSS contains a wealth of functions built right into the browser’s rendering engine that can perform everything from animations to typography and even ...

In this video I work through 129 examples of evaluating trigonometric expressions. We will evaluate the sine, cosine, and tangent using angles from the unit circle. To do this I will sketch each angle ...

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 ...

👉 Learn how to evaluate trigonometric functions using trigonometric identities. Trigonometric identities are equalities that involve trigonometric functions. We will focus on the cofunction ...

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 ...
