This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the ...

Vector mathematical illustration of sine curve in graph or chart and unit circle showing the sine graph. Gonometric or goniometric function. The icon in blue color is isolated on a white background.

In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where \(a\) is called the phase angle. This is when the graph of the function has been ...

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) ...

For example, in a typical mathematics graph, (0,0) is located at the center of the graph / page / diagram. This Demo Program shows a graph with (0,0) being at the center of the Graph area rather than ...
