Therefore, the area bounded by the given curve is 1/4 units.
Example 15.15 Find the area bounded by the cycloid x = t - sin t, y = 1 - cos t with x axis, where t
being the parameter such that 0 £ t £ 2p.
Solution: The parametric equations of the given curve are x = t - sin t, y = 1 - cos t with x-axis,
where t being the parameter such that 0 £ t £ 2p.
Now, dx = (1 - cos t) dt.
Thus, the area bounded by the given curve is
