comment Hasse Digram Leveling
Okay. I wasn't sure about that. I also added the line by the way.

comment Hasse Digram Leveling
You're right. I was doing the diagram on computer and missed that, but there was a line on the homework and so that is not the problem.

comment Constant velocity of a sine function
So, Wolfram Alpha gives $x(t) = InverseFunction[EllipticE, 1, 2]((c_1-t)/sqrt(2), 1/2)$ as the solution where $c_1$ is an arbitrary constant. I am thinking there is not a simpler solution unfortunately. I honestly am not sure what this solution means.

comment Constant velocity of a sine function
That is exactly what I meant. It has been a while since I have dealt with parametric equations and I didn't actually realize that was what I was trying to do. I should be able to find what $x(t)$ should be equal to from what you just said. I will give my result in the next comment.

comment Defining the movement of an object on a 2-dimensional plane
I was thinking that there will be enough frames per second that I would use the Euler method, although I didn't actually know that was its name until after what you said.

comment Defining the movement of an object on a 2-dimensional plane
Thank you EuYu. That link was very helpful. It seems that they use velocity and direction instead of a velocity for the x and y axes but it seems accomplish the same thing. Maybe doing it with direction and velocity is easier though?

comment Is there a definitive guide to speaking mathematics?
Thank you for the link Prescott. I found Handbook for Spoken Mathematics very helpful. For quantities in the middle of a expression such as a(b+c)+d, I felt it was best to read them a times the quantity b plus c "plus" d. The plus in quotations would be read with an upward inflection.

comment Does anyone know a good hyperbolic geometry software program?
@StevenStadnicki I was looking for programs that do things similar to NonEuclid. It is the only program I know that does this sort of modeling and I wanted to know if anyone knows any other similar programs.
