About :

Simple explanation of the trigonometric functions sine, cosine and tangent. We will see how they are defined starting from the trigonometric circumference, what their graphs are and how they are connected to each other. Sine, cosine and tangent are the 3 most recurring functions in trigonometry, and based on them, several fundamental theorems of trigonometry can be stated. Understanding how these trigonometric functions are defined is therefore fundamental to be able to then carry out the trigonometry exercises.
