Homework Statement
A particle moves in the xy-plane so that its position at any time t, 0 =< t =< pi, is given by:
[tex]x(t) = \frac{t^2}{2}-ln(1+t)[/tex]
[tex]y(t) = 3sint[/tex]
-- At that time is the particle on the y-axis on the interval? Find the speed and acceleration vector of the particle at this time.

None?
The Attempt at a Solution
I'm actually lost -- I believe that when x(t) = 0 it will be on the y-axis but I must be doing the algebra wrong I can't seem to get an exact solution...
