How to Use Trig Functions in Excel. Excel has built-in functions for sine and cosine, the two core trigonometric functions, and for hyperbolic sine and hyperbolic cosine, their hyperbolic ...

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.

National 5 Working with the graphs of trigonometric functions Phase angle Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points.

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 ...
