where \({\theta}\) is measured anti-clockwise from the positive \(x\)-axis. As the point P moves anti-clockwise round the circle from (1, 0), the angle \(\theta\) increases until P returns to its ...

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 \(y ...
