Above, enter the role to derive. Differentiation variable and more can exist changed in "Options". Click "Go!" to showtime the derivative calculation. The result will be shown farther below.
How the Derivative Calculator Works
For those with a technical groundwork, the following section explains how the Derivative Calculator works.
Kickoff, a parser analyzes the mathematical function. It transforms it into a grade that is better understandable by a estimator, namely a tree (meet effigy beneath). In doing this, the Derivative Calculator has to respect the gild of operations. A specialty in mathematical expressions is that the multiplication sign can exist left out sometimes, for example nosotros write "5x" instead of "5*x". The Derivative Calculator has to detect these cases and insert the multiplication sign.
The parser is implemented in JavaScript, based on the Shunting-yard algorithm, and tin run directly in the browser. This allows for quick feedback while typing by transforming the tree into LaTeX code. MathJax takes care of displaying it in the browser.
When the "Get!" push button is clicked, the Derivative Computer sends the mathematical function and the settings (differentiation variable and order) to the server, where it is analyzed again. This time, the function gets transformed into a form that tin can exist understood by the estimator algebra system Maxima.
Maxima takes intendance of really calculating the derivative of the mathematical function. Like whatsoever computer algebra system, information technology applies a number of rules to simplify the office and calculate the derivatives according to the usually known differentiation rules. Maxima'due south output is transformed to LaTeX once more and is then presented to the user.
Displaying the steps of calculation is a bit more involved, because the Derivative Calculator can't completely depend on Maxima for this task. Instead, the derivatives have to be calculated manually step by step. The rules of differentiation (production rule, quotient rule, concatenation rule, …) take been implemented in JavaScript code. In that location is also a table of derivative functions for the trigonometric functions and the square root, logarithm and exponential function. In each calculation footstep, one differentiation operation is carried out or rewritten. For example, abiding factors are pulled out of differentiation operations and sums are split upwardly (sum rule). This, and general simplifications, is done by Maxima. For each calculated derivative, the LaTeX representations of the resulting mathematical expressions are tagged in the HTML code so that highlighting is possible.
The "Check reply" characteristic has to solve the difficult task of determining whether two mathematical expressions are equivalent. Their difference is computed and simplified as far as possible using Maxima. For instance, this involves writing trigonometric/hyperbolic functions in their exponential forms. If it can exist shown that the difference simplifies to null, the task is solved. Otherwise, a probabilistic algorithm is applied that evaluates and compares both functions at randomly chosen places.
The interactive function graphs are computed in the browser and displayed within a canvas element (HTML5). For each role to exist graphed, the calculator creates a JavaScript role, which is so evaluated in small steps in order to draw the graph. While graphing, singularities (e. thou. poles) are detected and treated specially. The gesture control is implemented using Hammer.js.
