The trig tour model tracks the angle and trigonometry evaluations for each of the functions sin, cos, and tan. It can be restricted to 'special angles', angles which result in 'neat' trigonometric ...

Note: This only works when \(x\) is measured in radians. We are now going to look at more complex trigonometric functions where we will use the general rule: \(\int {\cos (ax + b)dx = \frac{1}{a}} ...

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 ...

Trigonometry is the branch of math that studies triangles, with a particular focus on the relationships between angles and the lengths of corresponding sides. Interestingly enough, the trigonometric ...

Save guides, add subjects and pick up where you left off with your BBC account. Practise solving trigonometric equations in degrees or radians using CAST and its period to find other solutions within ...
