Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core ...

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

Each trigonometric function also has an inverse that can be used to find an angle from a ratio of sides. ... For example, Madhava’s 1400 ...

Functions with Corners: 2.1: Some examples of graphs with corners which I talked about in lecture. The tangent line to a graph does not exist at a corner. Algebraic Simplification: 2.3: When computing ...

However, it's still hard to get an intuitive sense of the relationship between the circle and the trigonometric functions and the triangles. That all changes with animated GIFs.
