I have two semesters of math classes to complete: Trigonometry and Calculus I. I have at TI-89 graphing calculator that I absolutely hate. Who the hell makes the interfaces for these things? 46 ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Learn about graphs of trigonometric functions in this National 5 Maths guide.

Learn how to solve trigonometric equations. There are various methods that can be used to evaluate trigonometric identities, they include by factoring out the gcf and simplifying the factored equation ...

In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where \(a\) is called the phase angle. This is when the graph of the function has been ...
