Types of operations are expressed as + (addition), - (subtraction), *(multiplication), / (division). There are a few things to note when defining functions: You may want several input values, and you may want the user to group some of those input values in curly brackets. Instead, you may need to carry out several steps of computation, using temporary variables. However, in may cases, you may find it impossible to define the function's value in a single simple formula. The simplest user-defined functions are the "one-liners", where the quantity of interest can be computed by a single formula. \) in Mathematica the correct syntax is f. That is, while in mathematical notation, we write \( f(x), This is like how we suppress the result of a command by typing = as was described earlier.īrackets. To suppress output, type a semi-colon ( ) at the end of input of your command. However, if f=3*x+1 is entered, then f is 7, f = 3a+3b+1, and f is 3x+1 because entering x_ allows me to plug in different values for "x-blank." To indicate that the argument is the product ofĪ and t. Ordinary parentheses are used exclusively for algebraic grouping. That is, while in mathematical notation, we write \( f(x), \) The symbol x_, pronounced ``x-blank,'' denotes a ``pattern'' named "x." For example, If one were to enterį =3*x+1, then f and f will not be evaluated, but g will be evaluated because x is set as the only variable that this function will accept.įunction evaluation in Mathematica is indicated by squareīrackets.
