👉 Learn all about evaluating trigonometric functions with triangles. In this playlist, we will learn how to evaluate, sine, ...

In this video we will explore how to graph the reciprocal function. We will do this by exploring the characteristics of cosecant, secant, and cotangent to comparing them to the reciprocal functions, ...

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 ...

In high school, you probably learned that trigonometric functions – like sine, cosine and tangent –can be derived, geometrically, from a circle (hence why trig functions are also known as “circular” ...

Many students think they've solved a trig equation when they get one answer (one size of angle \(x^\circ\)). However there's often more than one answer expected so be aware of this. Let's remind ...
