Calculus of Parametric Equations
Parametric equations can be quite handy, and we don't want to unravel them just to do Calculus. Some tricks can bend traditional derivative and integral methods to apply to parametric equations.
If \(y\) is a function of \(x\) as defined by the parametric relation \(y=3\sin ^{ 2 }{ t }\) when \(x=\tan { t } \), then determine the value of \(\displaystyle\lim_{ x\rightarrow \infty }{ y }\) .

The location of a dot \(P\) at a given time \(t\) in the \(xy\) plane is given by \((x,y) = (t - \sin t, 1 - \cos t)\). What is the distance traveled by \(P\) in the interval \(0 \leq t \leq 2\pi\)?
