WP 34s Solve  Richard Berler  04042013 I love how the WP 34s shows the value on screen of an integral as the iterations progress. It is neat to watch the answer converge on the final approximation. Would it be doable to implement this on solve on future upgrades (also emulator)?
Re: WP 34s Solve  Walter B  04052013 Yes, in principle. In integration, however, there is a sum approaching the integral  in solving there is a function value aproaching zero or an x approaching the root. Which value do you want to see?

Re: WP 34s Solve  Paul Dale  04052013 Due to the algorithm used, solve doesn't necessarily approach the root directly. Once the root is bracketed, one estimate can stay the same and wildly incorrect while the other converges. It would take extra code to figure out which to display  nothing too difficult of course. Look at trunk/xrom/solve.wp34s from the source repository. Since the 34S is in bug fix only mode at the moment, I'm not planning on improving the solver. The source is available, thus, anyone can code an improved solver and submit it for inclusion.
Re: WP 34s Solve  Richard Berler  04052013 Thanks! That makes sense. The root that is being converged upon is what I think would be neat. Thanks for the explanation.
