Conic Sections Question 538
Question: The parametric equation of the curve $ y^{2}=8x $ are
Options:
A) $ x=t^{2},\ y=2t $
B) $ x=2t^{2},\ y=4t $
C) $ x=2t,\ y=4t^{2} $
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
Parametric equations of $ y^{2}=4ax $ are $ x=at^{2},y=2at $
Hence if equation is $ y^{2}=8x $ , then parametric equations are $ x=2t^{2},y=4t $ .
