I know x=rcos theta and y=rsin theta
i can help
you are given r and theta ... whats left for you to do?
Well, um, I am given theta? I guess I need more guidance..
p = (r,t) and x = r cos(t) y = r sin(t)
Ok. I did not spend much time on this section, but integration techneiques and log stuff got most of my attention. So you are saying it is (5,0) then?
This is final exam review.
what is 5 cos(pi/2) ?
cos (pi/2) is 0 so 5*0 is 0.
(x,y) -> (0,5)
you simply had (y,x) instead of (x,y)
Yea, that way from looking at the possible answer choices and typing before thinking.
