numeric solving vs graph
Hello all, I had a quite simple problem, or so I thought. I needed to find the first 3 values of t for which dx/dt =0, with x(t) = 4 sin3t e^(-t). I put the equation on the stack, LS+Calc -> DERVX. It's some crazy formula filling up the display. Functions in ALG don't really make it look any better, so I leave... 29 Sep 2008 00:40

a Stopwatch for the 50...
I need to time some processes, usually 1-2 minutes, occasionally longer. I only need 1 second or so accuracy. How do I get the hp50 to be a stopwatch for me?
