Unfortunately, for many of us the terms sine and cosine (its partner) are associated with memorizing endless formulas in trigonometry class, which makes it hard to appreciate their mathematical ...

Plot tan, cot, sec and csc on the interval [-2Pi, 2Pi]. (Note that these functions all have vertical asymptotes.) You should know these graphs well. The trigonometeric functions are all periodic, that ...

Learn and revise trigonometric ratios of sine, cosine and tangent and calculate angles and lengths in right-angled triangles with GCSE Bitesize AQA Maths.

This area investigates how waves propagating in continuous media and on network-like structures, such as metric graphs, can be steered (control problems) or deduced from observations (inverse ...
