![]() I know I´m asking for how to do basically every step in my DIY Wolfram alpha calculator and for strangers to offer their time to help a stranger on the internet is asking for a lot. I wouldn´t think that it would be that hard to make the Audrino boot up into something like the android version of Wolfram Alpha and give a display output with two scrollable up and down buttons. The problem I have with this is that I most importantly am unsure of how to make the buttons on the calculator send an input to the Audrino since the buttons on the calculator will be hard to make functional after I rip out the normal circuit board and if I try to modify the buttons on the circuit board by connecting the circuit board to the Audrino it wouldn´t be enough space.Ģnd problem is, of course, making the code, I only understand the very basics of LUA and Phyton so coding it would be a challenge for me but something I hopefully think I Could overcome. Then make the numbers on the calculator input the proper numbers and symbols in the display, since the answer is solved and shown step by step I would need to make the steps scrollable on two up and down buttons. Then I would need to code it so that the Audrino would boot up in the Wolfram Alpha program or code it in web-based API linked to their site. So I guess I would just need to rip out the circuit board in the calculator and install an Audrino mini in it. Since Wolfram Alpha program is on Android and Windows and can also be used from their website. The thing is I´m far far far from a pro at Audrino project´s and I don´t know how much effort it would take or what to really do to make it work. For those who don't know Wolfgram alpha is a calculator App and website that shows you how to solve any math problem step by step, if I could make that program run on a modified calculator it would make my maths easier to calculate and more understandable, it would just be very handy in general. I’ll continue to make posts about WolframAlpha so those of you who do not have access to a graphing calculator have an alternative way to make graphs, calculate values, ect.I want to modify an HP 10bll+ calculator with something like an Audrino mini to include the Wolfgram alpha program. This gives the same output as TRACE on a graphing calculator. Now add “where x = 20” on the command line and you will see: This will make WolframAlpha graph the formula by itself. We can do this by clicking on the formula above. ![]() Often you are interested in evaluating the model above at a particular point. Not only does it give a decimal…it also gives the exact answer in terms of fractions! We can find this point of intersection by modifying the input to WolframAlpha with the command “intersections”: To see this point of intersection, extend the graph by modifying the input to WolframAlpha as you see below. You can see that these lines are going to meet. If you want to graph two formulas simultaneously, add another formula with the word “and” as you see below. Enter the text you see below into WolframAlpha followed by Enter. It is best to show some examples to get you started.įor instance, suppose you want to graph the function y = -5.686 x + 676.173 in a window from x = 0 to x = 25. When you go to this website, you’ll see a box in which you can enter commands to help you do mathematics. The trouble is knowing how to use it to do just about anything. This website is the Internet’s leading computational engine. ![]() But luckily there is another option!Īnother option is the website WolframAlpha ( ). None of them work identically to a graphing calculator which makes them difficult to support. Most will graph formulas, but may or may not graph data and fit data to lines. I have had a hard time finding just one that does everything we need. ![]() If you have an Android phone or IPhone, there are a huge number of free apps that are available. In addition to Excel, there are many online graphing tools available. A number of you have asked me about alternatives to a TI graphing calculator.
