Range Variables A variable may be defined to automatically contain a range of values For example: if you want variable i to go to 0 to 10 enter this: For example: of you want j to go from 0 to 10, but in increments of 0.25 enter this: The comma after the zero will display the appropriate increments To see ALL of the values click INSIDE the box and use the scroll bar. The unit menu should open and you can choose the unit you want Hit enter after you choose the correct unit to see the correct unit conversion in the units you selectedĮntering Text Entering text regions in MATHCAD can be done in three different ways Typing a quotation mark By selecting insert Text Region from the pull down menu By pressing the space bar after typing parts of the text.
Enter: MATHCAD defaults to the metric unit “meters” Note: MATHCAD IS “CASE-SENSITIVE”Ĭhanging units To change the unit: Click on the value Click on the black placement bar at end of unit. There are two different methods for inserting units Using the insert-unit command from the menu By typing the unit next to the variable valueĮntering Units Enter: You should notice that MATCAD automatically recognizes the unit inches. MATHCAD units MATHCAD understands and processes a variety of units from different systems. Inserted with the “.x, this represents the VELOCITY in the HORIZONTAL DIRECTION! Inserted with “.” sign ( a period) INDEX SUBSCRIPT – Used to access or define indices within an array. Text and Input Subscripts The TWO types of subscripts are: TEXT SUBSCRIPT – Used for visualization purposes only. Select an equation to move by first clicking on the equation Move the cursor to the END of the equation until a HAND cursor is displayed Click and drag the equation to a new location You can also edit the equation(s) by using the arrow keys to move the BLUE cursor or you can use the mouse Just keep in mind that MATHCAD work everything from left to right and from top to bottomĪs you enter an equation a text cursor marks your input point The input point can be moved using the space bar The arrow keys can also be used to move the text entry cursor If you have the input point at the beginning of an equation, when you hit delete it will delete the whole equation The Equal Signs Move the + edit cursor to the upper left of the scratch pad.
T) Global Assignment Similar to regular assignment operator (:=) Available on the evaluation toolbar Global assignment equality will be evaluated first, regardless of position on worksheet (e.g.x = 4) Symbolic Equality ( BOLD =) Enter by simultaneously hitting Ctrl and = keys Symbolizes a relationship between variables(e.g. MathCAD returns the underlined result after the = has been typed (e.g. x := 4) Display equals/calculate value (=) Enter by hitting the equals key Used to display the value of a variable. MathCAD includes four discrete equals signs: Assignment (:=) Enter by hitting the colon key Used to define parameters (e.g.
The “math” toolbar allows you to view additional toolbars: functions, graphs, etc.
