При вводе формул в текстовые окошки используется нотация языка BASIC и правила ввода формул в ячейки табличного процессора Excel:

Возможен доступ ко ВСЕМ функциям и операторам Mathcad, если это потребуется!

Примеры ввода формул: (a+b)*sqrt(sin(1.23)*pi/e^x)/n!   (a+b)/(c-1.25E-7)  p*sin(pi*30/180)

 

English

The string expression uses the normal conventions for linear expressions. The infix binary operators for addition, subtraction, multiplication, division, and exponentiation are represented by +, -, *, /, and ^. The unary prefix operators for identity, negation, and conversion to degrees are represented by +, -, and °. The unary postfix operators for factorial and conversion from degrees are represented by ! and °[1]. Parentheses (()) are used for grouping. Normal (according to me) order of operations applies otherwise.

Functions are written as a function name followed by a parenthesized list of argument values. The following functions are provided: sin, cos, tan, asin, acos, atan, atan2, abs, sqrt. They are defined to be the Mathcad functions of the same name or the commonly used functions of that name.

Numbers are written in normal decimal style. Decimal exponents, introduced by e or E, are allowed. There are three variables, x, y, and z, used to represent the elements of the argument vector to Eval. The variables pi and e are constants, with the Mathcad defined values. Variable (and function) names are case sensitive. There is no provision for user defined variables
