Has anyone solved this yet?

The equation is a bit of a joke. Follow the link to the carnival submission that I was playing around with, and you will see the solution there.

Or rather, you will when the website is working correctly. For some reason, the graph will not display in my browser window today. It worked just fine last week. I wonder what’s the glitch?

I see X and Y, and it looks like the highest power is 4. The last term has to equal the rest of the equation, because T-L=0. T=the rest of the terms, L=the last term. So you can move L over to the other side. Now it becomes a very long string of multiplying and squaring and simplifying.

Yes, I am actually attempting to solve this. Now, I don’t expect to finish, but I’ll give it a go. Should I solve for x or y?

Well, Gecko, when you have an equation with both

xandy, then you have to solve for thepairsthat make it true. Generally, you will end up with some sort of coordinate graph, since it’s usually impossible to list all the pairs. A graph gives a picture of all the solutions.But the highest power isn’t 4, because each line is multiplied by the next line. Notice the dots at the beginning of each line? And watch out for those funny brackets. They mean “the largest integer less than___”, and they are probably going to make the calculations more than you can deal with, even as good as you are at math. Interesting to try, though.

You might find this interesting. It’s related to the graph, but much simpler:

*The Equation of a Line SegmentSo.. What’s the answer?

The link (which isn’t working tonight, so it may have gone offline) was an inverse graph generator. You put in words, and it gave you a monster mess of an equation that would graph them. This equation said “LETS PLAY MATH” — the name of my blog.
