3.3.2 Coordinate geometry in the (x, y) plane (A-level only)

Card 1 of 20

For x=2tx=2tx=2t, y=t2−1y=t^2-1y=t2−1, what point corresponds to t=0t=0t=0?

A

Under downward gravity, the vertical position is y=y0+uyt−12gt2\boxed{y=y_0+u_yt-\frac{1}{2}gt^2}y=y0​+uy​t−21​gt2​.

B

(0,−1)(0,-1)(0,−1)

C

(−4,3)(-4,3)(−4,3)

D

x=5cos⁡t,y=−5sin⁡tx=5\cos t,\quad y=-5\sin tx=5cost,y=−5sint
