👉 Learn how to graph a cosine function. To graph a cosine function, we first determine the amplitude (the maximum point on ...

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.

An icon in the shape of a lightning bolt. Impact Link Trigonometry is the branch of math that studies triangles, with a particular focus on the relationships between angles and the lengths of ...

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 ...
