Please help! I am confused. Comparing Plane Curves In Exercise 38, determine any differences between the curves of the parametric equations. Are the graphs the same? Are the orientations the same? Are the curves smooth? Explain. 38 (a)
x=2cos\theta
y=2sin\theta
(b) |)
t|
||
y=(1)/(t)
(c)
x=\sqrt(t)
y=\sqrt(4-t)
(d)
x=-\sqrt(4-e^(2))
y=e^(1)
