Trigonometric graphs
Watch this video to learn about graphs of trigonometric functions.
The sine and cosine graphs
The sine and cosine graphs are very similar as they both:
- have the same curve only shifted along the x-axis
- have an amplitude (half the distance between the maximum and minimum values) of 1
- have a period (size of one wave) of 360˚
The tangent curve
The tangent graph:
- has an amplitude which is undefined as the curve tends to infinity both upwards and downwards
- has a period of 180˚
