Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with the positve x-axis. cos(θ) ...

This program allow the user to generate a sine or a cosine graph by only asking the user for the graph properties. The properties of the sine and cosine function are: Amplitude : Any real number ...

As the point P moves anticlockwise around the circle from 0°, the angle θ changes. The values of cos θ and sin θ also change. The graphs of y = sin θ and y = cos θ can be plotted.

Trigonometry - Edexcel Trigonometric graphs - Higher The three trigonometric ratios; sine, cosine and tangent are used to calculate angles and lengths in right-angled triangles.
