An animated guide to using trigonometry. Trigonometric terms are explained and examples are used to show how to find unknown angles and sides for right-angled triangles. Use as an introduction or ...

Our modern understanding of trigonometry harks back to ancient Greek astronomers studying the movement of celestial bodies through the night sky. But in 2017, I showed the ancient Babylonians likely ...

What do you think the graph of \(y = \cos 2x^\circ\) would look like? amplitude = 1, so the distance between the maximum and minimum values is 2 number of waves = 2 (period is 360˚ ÷ 2 = 180˚) graph ...
