Sine, cosine and tangent functions are periodic functions, meaning they repeat themselves at regular intervals. This interval of repetition is known as the period of the function, and this periodicity ...

The app can also solve equations that use more complex formulas, such as the trigonometric functions of sine, cosine and tangent. You need to include the equals sign (=) at the end of each ...

They provide a versatile framework for solving equations, visualising data, and making informed decisions. This resource revises linear functions, graphs and equations and within linear functions, ...
