Introduction II. Inputs III. Initial Calculations IV. At least one expression in the loop body must change the condition expression, x, so that it becomes false. Otherwise, the loop executes indefinitely. Additional Information • You can type the word while and then press Ctrl+J to convert the word to a programming operator with all its placeholders. Example: Looping and Control Functions and Arrays in Mathcad. Mathcad is a tool to arrange, calculate, and visualize engineering calculations and functions can help with reusing expressions in subsequent evaluations. Use the following worksheets to step through example problems related to using functions and matrix operations effectively in a Mathcad worksheet. For Loop Use For loop when you know exactly how many times you want to execute the loop body Click for button or press [Ctrl+"]. Do not type the word "for" In the placeholder to the left of the , enter the iteration variable In the placeholder to the right of the , enter the range of values to be taken by the iteration variable Some examples and practice: (1) Exercise: plot the functions y(x)=x^2 and y(x)=x^4 on the interval [-1:1]. (Experiment with the increment between x values to get "smooth" curves for your plots.) (2) Mathcad has lots of "special functions" built in. For example, trigonometric functions like sin and cos. Here is how to plot sin(x) over one period: Create a For Loop Mathcad - Prime 5.0, Prime 6.0, Prime 7.0 Summary A for loop iterates a calculation, or set of calculations, a fixed number of times. The for loop construct contains three placeholders, with the bottom placeholder indented. On the first line of the construct, the first placeholder contains an index. A for loop is used to calculate velocity for 96 pipe lengths. The guess for each call of function V1 is 1. i095:= ..

Title: Mathcad - Example_10.6_V2000 Author: johns Created Date: As long as you know the logic that you want to execute you can write a program. Within the Math tab click on the Programming button which allows you to construct; such as if statement, also if, else, else if, while and for loop, etc. When writing a program in Mathcad all the math still goes into the program using native math notation-allowing For Loop in Mathcad addnumbers n() s 0 Mathcad - Programming_examples Author: cmartine Created Date: 11/9/2010 12:09:42 AM The following math regions are examples of simple formulas evaluated by Mathcad. Mathcad is a WYSIWYG (what-you-see-is-what-you-get) word processor for mathematics. Of course, the most powerful features of Mathcad have to do with math regions. The rest of this tutorial will concentrate on these features. Math regions 3 You simply type in math with your keyboard, using numbers and standard operators like add, subtract, multiply, and divide, with parentheses, exponents, and so on. As a beginner, though, you have to know the difference between two different types of equals signs. For the four basic operations, use +, -, *, and / right from the keyboard. 1.837 10.3 100 35 =2.3142353232 The standard engineering and math functions are built in. log 134
