Trigonometric functions are elementary functions. They have inherent periodicity, that is, repeatability on certain segments of the coordinate plane. The period is denoted by the letter T.
Trigonometric functions include:
function of sine: y = sin(x), the graph of which is sine wave
- the cosine function y = cos(x), the graph of which is a cosinusoid
- function of the tangent y = tg(x), for graph y=tan(x) the graph of which is the tangensoid
- the function of cotangent y = ctg(x) for graph y=cot(x) whose graph is the cotangensoid.

Sinus and cosine graphs are curved lines along the X axis.
Tangent and cotangent graphs are many curved lines along the Y axis.
