![]() ![]() You can do this, as above, by simply leaving the unknows in the matrix as letters. Wolfram can also solve simultaneous equations in matrix form (linear systems). or a * Operationsįinding the determinant, minors, cofactors or inverse of a matrix is as simple as typing determinant, minors, cofactors or inverse, followed by the matrix itself. Addition uses a + between matrices, and multiplication needs a. Addition & MultiplicationĪddition, multiplication and scalar multiplication work pretty much as you would expect them to. In WolframAlpha, matrices are written with curly brackets for each horizontal row, with rows separated by commas, and a pair of curly brackets surrounding the entire matrix. IMPORTANT You will need to have a WolframAlpha Pro account to use Wolfram effectively. Probably more relevant for university courses, but WA also diagonalizes matrices/finds their Jordan canonical form.Matrices | Maths Module Resources Maths Module Resources Resources for DE1 Mathematics course Matrices So a regular plot like plot x^2 from -5 to 1 becomes Plot (opens new window) gives 0, 0, 0, -3.642, 68.64. When plotting functions, we don't always want the range that WA suggests, so plot x^2 from -5 to 1 (opens new window) would change the range from the default to the interval from -5 to 1.įor simpler plots, writing in plain English what we want works just fine, but for more complex or intricated plots, we will be better of using the Mathematica syntax. ![]() There are several different types of plots you can ask WA to do, but perhaps the most basic one would be to plot a simple function from the reals to the reals, like plotting x^2 (opens new window), which can be done by typing in plot x^2 or plot Power. Trigonometric functions have the usual names, but capitalized for example, Tan, Sin, ArcCos are respectively the tangent, sine and arc-cosine functions.The logarithm and the exponential function are respectively written as Log and Exp.The factorial operator can be written as n! or as Factorial.The square root is Sqrt, and the n-th root of x is given by Root, so the cubic root of 8 would be found by typing in Root (opens new window).To find the remainder of a division, either type in x mod m or use Mod.The power operator ^, used as x^y, which can also be used as Power.The usual addition +, subtraction -, multiplication * and division /.WolframAlpha can, of course, be used as a pretty advanced calculator. One final very important hint is that if you have Mathematica, you can get step-by-step solutions to limits, integrals and derivatives (only to name a few) by starting a command with =. This is relevant because WA supports a subset of Mathematica's functions. So if you click this -> What is the 345th decimal place of pi (opens new window) you will see what WA answered me when I asked for the 345th decimal place of pi (it's 5, by the way).Īnother important thing to notice is that you don't have to follow a strict syntax when asking things to WA, even though the more you can facilitate WA's life, the better.Īlso note that Mathematica - the language developed by the creators of WA -, uses for function calls, instead of (), and all function names are capitalized, so Sqrt would give you the usual square root function, that in many languages would probably be used as sqrt(n). Through this guide, blue letters with a gray background give a link to a WA query. For example, following this link (opens new window) you can see what WA told me when I asked him who the US president is. Whenever you input something into WA, you get the link of your query, so that you can actually share what you asked and the answer given pretty easily. WolframAlpha's knowledge engine can be accessed online through (opens new window) but if you have access to a license, perhaps through your university/research center/company, you might want to install Wolfram Mathematica (opens new window), "a modern technical computing system spanning most areas of technical computing - including neural networks, machine learning, image processing, geometry, data science, visualizations, and others". WolframAlpha is most notable for its capabilities regarding mathematics and it can be a very powerful tool to help you with your computations. WolframAlpha (opens new window) (WA) is a computational knowledge engine, which is a very fancy way of saying that WolframAlpha is a platform that can answer your questions.
