First handful of questions have pupils solving trigonometric equations by sketching graphs to identify which quadrants solutions lie in and using the symmetry of said graphs to find the value of these ...

A fully animated lesson on solving trigonometric equations in radians using graphs. This was taught for an AS group sitting the AQA spec, which the textbook exercises relate to. Starter focuses on ...

In this video, we provide essential "math help" by demonstrating "how to graph cosecant" functions, specifically y=csc(2x).

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, ...

Most problems in trigonometry involve finding the length of an unknown side of a triangle when given one angle and one side or finding an unknown angle in a triangle when the lengths of two sides are ...
