Trigonometry is a branch ... the hypotenuse From our ship-mast example before, the relationship between an angle and its tangent can be determined from its graph, shown below.

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 ...

Master trigonometric equations for Olympiad success! In this tutorial, we’ll walk you through essential techniques to solve challenging trigonometric problems. Perfect for students preparing for ...

but many fail to make the leap on how crucial circles are for trig functions. With static graphs and equations, it's possible to get a handle on the rules of what various functions do and mean.

Due to the vastness of the subject, mathematicians have devised formulas to simplify equations ... glossaries of Inverse Trigonometric Functions, along with necessary examples.
