With static graphs and equations ... sense of the relationship between the circle and the trigonometric functions and the triangles. That all changes with animated GIFs. Change over time is ...

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 ...

Trigonometric graphs can be sketched when ... relationships in degrees Trigonometric functions can have several solutions. Sine, cosine and tangent all have different positive or negative values ...

Trigonometry ... We want the slope, but all we have is the angle. What we need is a relationship that relates the two. This relationship is known as the “tangent function,” written as tan ...
