Nah we’ll prob get 1/3 for it ://

How did you guys go about finding the angle in projectile? I found dy/dx on the cartesian equation at the x-coord for A, then used angle between two lines with y=-x. Got 45° tho

I got A for mc10

Use it if they give an acceleration equation with respect to displacement (x)

1997 6b and 1998 2b... but I doubt it

cot^2(kpi/(2m+1)) question However, I am unsure whether it is necessary to show x=cot^2(kpi/(2m+1)) is not a solution to p'(x) hence no multiple roots for p(x) meaning p(x) has m distinct roots

Here's the x=p/q one if it helps

Is there a way to watch if we missed it?
