This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the \(y ...

Most trigonometry students look at triangles on a flat surface. However, people from ancient astronomers to modern navigators calculated the arc lengths and angles of triangles on a sphere. They used ...

You can also plot graphs for trigonometric equations (equations that use sine, cosine, and tan, etc.), establish graphs for linear and quadratic inequalities, and even plot graphs for various ...

Calculus is often introduced to students during their high school years, and for many, it can feel like a giant leap in ...

standard functions and their graphs, limits, continuity, tangents, derivatives, the definite integral, and the fundamental theorem of calculus. Formulas for differentiation are developed and include ...

The original video can be viewed here. For many high school students returning to class this month, it may seem like geometry and trigonometry were created by the Greeks as a form of torture.

It has a variety of useful applications and functions as well as a complete suite of graphing abilities, making it perfect for everything from calculus to trigonometry and beyond. It's a massive ...

everyone in class had a TI graphing calculator. In some ways this was better than a cell phone: If you wanted to play BlockDude instead of doing trig identities, this was much more discrete.

The theory of random graphs provides a necessary framework for understanding their structure and development. This text provides an accessible introduction to this rapidly expanding subject. It covers ...

How have energy sources changed since 2001? By The Learning Network A new collection of graphs, maps and charts organized by topic and type from our “What’s Going On in This Graph?” ...

Death to triangles!” Luckily, triangles survived nonetheless—and thrived. In “Love Triangle: How Trigonometry Shapes the World,” Matt Parker recounts, for instance, how computers were a ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the \(y ...
