This circle has the centre at the origin and a radius of 1 unit. The point P can move around ... depending on the value of \(\theta\). The graphs of \(y = \sin{\theta}\) and \(y = \cos{\theta}\) ...

To find the equation of a circle when you know the radius and centre, use the formula \({(x - a)^2} + {(y - b)^2} = {r^2}\), where \((a,b)\) represents the centre of the circle, and \(r\) is the ...
