Consider a circle, radius $a$, center at the origin. Let $P(x, y)$ be any point on the circle, and let the angle between $PO$ and the x-axis be $\theta$, then $x=a\cos\theta$ and $y=a\sin\theta$.
These equations, which give the coordinates of any point on the curve in terms of $\theta$, are called parametric equations, and $\theta$ is called a parameter.
Find the Cartesian equation of the locus given parametrically by the equations $x=\sin\theta$, $y=\sin2\theta$

Equations and Inequalities
Task Background: Equations and inequalities are very useful in the real world. For example, when computing hours worked, there is a difference between working exactly 40 hours (equation = 40) or more than 40 hours (inequality > 40), if overtime is applicable.
Scenario: You have just graduated college, and you have started your first project at your new job. Your boss informs you that you are responsible for the Equations and Inequalities sections of the project to ensure that the company is going to stay within some limits of cost.
