![]() ![]() The rules of differentiation (product rule, quotient rule, chain rule, …) have been implemented in JavaScript code. Instead, the derivatives have to be calculated manually step by step. Maxima's output is transformed to LaTeX again and is then presented to the user.ĭisplaying the steps of calculation is a bit more involved, because the Derivative Calculator can't completely depend on Maxima for this task. ![]() Like any computer algebra system, it applies a number of rules to simplify the function and calculate the derivatives according to the commonly known differentiation rules. Maxima takes care of actually computing the derivative of the mathematical function. ![]() This time, the function gets transformed into a form that can be understood by the computer algebra system Maxima. When the "Go!" button is clicked, the Derivative Calculator sends the mathematical function and the settings (differentiation variable and order) to the server, where it is analyzed again. MathJax takes care of displaying it in the browser. This allows for quick feedback while typing by transforming the tree into LaTeX code. The parser is implemented in JavaScript, based on the Shunting-yard algorithm, and can run directly in the browser. The Derivative Calculator has to detect these cases and insert the multiplication sign. A specialty in mathematical expressions is that the multiplication sign can be left out sometimes, for example we write "5x" instead of "5*x". In doing this, the Derivative Calculator has to respect the order of operations. It transforms it into a form that is better understandable by a computer, namely a tree (see figure below). Observe how there are no global variables: each function accepts parameters and returns specific output values.For those with a technical background, the following section explains how the Derivative Calculator works.įirst, a parser analyzes the mathematical function. N2 = random.randint(min(operand_range), max(operand_range)) N1 = random.randint(min(operand_range), max(operand_range)) Op_sym, op_func = random.choice(binary_operations) """Generate a pair consisting of a random question (as a string) To address those issues, as well as the code repetition you mentioned, I'd write the program like this: import operatorĭef random_question(binary_operations, operand_range): function is the least-informative name possible for a function.While firstName and lastName are somewhat excusable (they are entered once by the user, and never change subsequently), you really shouldn't use globals for transient state like ans, question, etc. The endMenu() function is improperly recursive.Rather, you have some free-floating code outside of any function, and the main function is actually called endMenu(), which is surprising. Your main() function is not really the main code of your program.Please try again.")īesides the obvious code repetition that you mentioned, a few salient issues deserve mentioning: Options = int(input('''Press '1' to view users' scores,Įlif options = 2: #starts the game loop again because it's in a functionĮlif options = 1: #displays everything on the.
