Q. Which one of the following equations represents parametrically, parabolic profile?
Conic Sections
A
$x=3 \cos t ; y=4 \sin t$
B
$x^2-2=-\cos t ; y=4 \cos ^2 \frac{t}{2}$
C
$\sqrt{ x }=\tan t ; \sqrt{ y }=\sec t$
D
$x=\sqrt{1-\sin t} ; y=\sin \frac{t}{2}+\cos \frac{t}{2}$
Solution:
Correct answer is (b) $x^2-2=-\cos t ; y=4 \cos ^2 \frac{t}{2}$
