In addition to these trigonometric functions, further mathematical functions are also available, many of whom have been available for years now, such as calc(), min() and max().

Working with the graphs of trigonometric functions Trigonometric graphs Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points.

The graphs of sine and cosine are included as well. The three principle trigonometric functions. (Image credit: Robert J. Coolman) ...

Interestingly enough, the trigonometric functions that define those relationships are also closely tied to circles. Needless to say, this makes trig one of the hardest topics in math for students ...
