That should suppress the error, assuming you are comfortable with the fact that sometimes Mathematica will make this maneuver to solve equations that are input as if they are numerical, but are better solved symbolically.

In the end, if ratnz is an issue, start your code with: Off The second solution is valid when tc<0 and tc <= c <= -2 tc (or when c=tc=0, which is the degenerate solution that includes both cases). (tc = 0) only when c=0 which should be obvious. Even correcting these minor issues: f1 = ta - tb + c į2 = ta*tc + ta*tb + 0.5*ta^2 + tb*tc + 0.5*tb^2 Find more Mathematics widgets in WolframAlpha.

However, that's not really part of the issue. Get the free 'System of Equations Solver ' widget for your website, blog, Wordpress, Blogger, or iGoogle. Second, these functions do not require delayed evaluation, so the := is superfluous. Better, generally, to use lowercase letters for n, c, d, etc. I believe there are a few ways to improve this, at least one of which has already been mentioned.įirst, capital C is a built-in symbol.
There is a similar distinction between 0.5 and 1/2. "0." represents the floating point real number that's just about as close to zero as Mathematica can figure.

Posted in Software Hacks Tagged homework, math, wolfram alpha Post navigationīuilding A Swiss Army Lab With Software Defined Instrumentation 32 Comments If Google and Alexa are not mathematical enough for you, perhaps you’d be happier with Wolfram. If you want something more specific, try OneSolver. Wolfram can do a lot of electronic problems. For example, if a resistor doubles in value, what happens to the gain of the amplifier? Does it double? Halve? Change exponentially? Seeing the steps worked out and the graphs that Wolfram provides can help you visualize things like that.
There is at least as much value in developing intuition about physical processes. We often say that getting the right answer is only part of the value for math. Pressing next will show the actual work and let you move to the next step. In some cases, the step starts with a hint so you can try working the problem yourself. If you click the link you’ll see the answer along with an orange button that says “step-by-step solution.” This leads to a wizard-like screen that shows each step.

There are examples, but be aware that for general use, you do need to upgrade to pro (about $6 a month or less if you are student or teacher).Īs an example, consider factoring a simple polynomial.

However, a recent update shows more intermediate steps and also covers more kinds of problems in a step-by-step format. Granted, the site has always shown work on some problems. We aren’t suggesting you cheat at homework, but we did notice that Wolfram Alpha now shows more of its work when it solves many common math problems. If you’ve grown up where a computer is a normal part of school work, that might annoy you since a lot of tools just give you an answer. The bane of math students everywhere is the teacher asking for you to show your work.
