” Change Number Of Decimal Places to zero and look at the displayed results. Choose “General” format, and uncheck “Show Trailing Zeros. Type the following on a blank Mathcad worksheet: a Next, on the Calculation tab place a check in the “Use ORIGIN For String Indexing” box. Next, set the Warnings tab so that all check boxes are checked. Change the “Default Worksheet Location” to a location other than the Mathcad default. 10įrom your differential equations text book, solve 5 first order ordinary differential equations using the Odesolve function. Tan(a*x) (assign a = 0.8 for the definite integral in the next problem) 9Įvaluate the above integrals as definite integrals from the values of a = 1 and b = 5 (For x*sec(x 2 use a = 0.1 and b = 0.2). X n (assign n = 5 for the definite integral in the next problem) b
Use the Symbolics menu and the symbolics operator to integrate the following: a X n (assign n = 5 for the numeric differentiation) d Use the Symbolics menu, the symbolics operator, and numeric differentiation (at x = 5) to differentiate the following (Note: Assign the numeric values at the end of your worksheet, so that the symbolic evaluations will not be affected by the numeric values.): a Use numeric integration to solve the same problems as above.
5įrom you calculus textbook, use the live symbolics operator to solve 10 definite integrals. Use the live symbolics operator to solve the same problems as above. 3įrom your calculus textbook, use the Mathcad Symbolics menu to solve 10 indefinite integral problems. Now open a new worksheet to see if the new worksheet is based on your custom template.įrom your calculus textbook, use the Mathcad Symbolics menu to solve 10 differentiation problems. Make a copy of your own custom template file. Rename the Normal.xmct template file to Original Normal.xmct. Did the custom units come into the new worksheet? 5 Open a new worksheet based on this template.
Place these custom units on the right side of the right margin, and save your template. Refer to the custom units you created in Chapter 4 practice exercises. Open the template file you created in exercise 3. List the characteristics of your new template. Include the following in your template: header, footer, new math styles, new text styles, custom worksheet settings, and custom number format settings. Start your template from a worksheet based on the Blank Worksheet template. 3Ĭreate and save your own custom template. 2Ĭreate the EM US template discussed in this chapter. There are two main differences from a regular Solve Block:Ģ) Use the symbolic evaluation operator (right arrow) with the Find function.Ĭreate the graph of the function f (x) (Table 1) and determine one of the roots of the equation approximately.Additional problems and applications can be found on the companion site: 1Ĭreate the EM Metric template discussed in this chapter.

This means that whenever you evaluate an expression, Mathcad returns one or more numbers, as shown at the top of Figure 14-1. You’ve seen Mathcad engaging in numeric calculations.
