👉 Trigonon is a type of mathematical expression that represents an angle in the plane. It consists of two variables, usually denoted by x and y, and it can be used to represent angles between two axes. The general form of a trigonon is: x = sin(y) y = cos(x) where x and y are the coordinates along the x-axis and y-axis respectively. The sine function (sin) and cosine function (cos) are important in trigonometry, as
