Thanks for the help, but I have to type my answer in a text box and I dont have any way of explaining that in a text box. Can you help me with that?

anonymous · Answer

From the second and third plots, t = 1.91 and t = 4.37 rounded to the nearest 1/100th respectively.

By the way, the plot lines in the last two plots have very little curvature because of the magnification.

Does the information above answer your concerns?

anonymous · Answer

The plots were generated by a computer program, Mathematica 8 Home Edition.

anonymous · Answer

Does that mean that t is 1.91 or is it 4.37 when you solve the equation?
