Hello all! In my precalculus class, we've just begun working with parametric equations. Most everything seems to make perfect sense, except that sometimes our answers don't agree with the calculator. I'm not sure if it's because our teacher didn't teach us this (he tends to leave things out for us to figure out), our book doesn't mention it, or if it's because I just am missing something. Here's an example: The book gives me: Code: x = t + 2 y = 1 + 3/t Code: t = {2, 1, 0, 1, 2} x = {0, 1, 2, 3, 4} y = {1/2, 2, undefined, 4, 5/2} What exactly is going on? Do I need to change what the calculator calls the "Tstep" to see it all, or is there something I'm missing? Or is the calculator wrong? Or am I just overreacting and need to not bother? Any help? Thanks for anything.

TStep, probably, yes. Make TStep smaller. Zoom in, too.
