Questions
Which of the following parametric equation does
not represent a parabola
a
x=t2+2t+1,y=2t+2
b
x=at2−2t+1,y=2at−2a
c
x=3sin2t,y=6sint
d
x=asint,y=2acost
detailed solution
Correct option is D
x=aT2,y=2aT represents a parabola.in(a) a=1,T=t+1, in (b) a=a,T=(t−1)in(c) a=3,T=sint. But in (d)if 2aT=2acost⇒ T=cost which does not satisfy x=aT2Talk to our academic expert!
