  1. A 6-minute slide show to illustrate the main features of Mathcad documents are used forengineering and financial mathematics calculations.They are intuitive, easily audited and portable. If what you see here looks like a better way to do your job,contact HRS today. click here to begin © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  2. Here is a screen picture of a very simple Mathcad document Mathcad allows you to document your calculations and easily check them nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  3. Text is placed anywhere on the page nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  4. You can define named mathematical variables nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  5. New variables can be based on any mathematical expression of existing variables nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  6. If you type the name of an existing variable, followed by the = sign, Mathcad gives you the present value of that variable nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  7. If you then change any variable that is used to define other variables, the values of the other variables are automatically updated nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  8. Mathcad allows you to incorporate spreadsheets Here we do it to show how much harder to read a spreadsheet is than Mathcad When you double click on the embedded spreadsheet, you can activate it in Mathcad nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  9. And here is the expression you need to interpret! Here is the value of z Which do you prefer? nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  10. Electrical calculations often use complex numbers Sometimes you need exact answers This is easier to calculate in a microprocessor nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  11. Very often you will use Mathcad’’s own built-in functions, that cover many areas of calculation Define your own area function Now use it with a value of r -including units, if you want Functions can use other functions nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  12. Mathcad allows the use of units in its calculations, using the abbreviations you are used to. It will automatically take care of unit conversions and output its results in SI units. Set the values of variables Double click the units place-holder to change the units, if necessary Define an expression When you show the result, Mathcad knows this is an energy, and shows it in Joules nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  13. Insert a data entry type Excel component The data in the spreadsheet is stored in a matrix called M Choose a 3D graph type Type M to connect the data with the graph nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  14. Choose an Excel component from here See the Excel data within Mathcad Getting specific data from Excel Tell Mathcad names you want for the vectors Say where the data is nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  15. You can plot your data, easily Choose a 2D Scatter Plot Replace the place-holders by the Year and Count variables nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  16. Here we solve a system of nonlinear equations numerically. We'll give the solver guesses for the variables to start the process: “Given” and “Find” work in pairs These equations set allowable values of x and y The Find expression gives values of x and y that fit the conditions nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  17. When you do integrations, the method appropriate for the expression must be chosen. I right clicked on the integral sign to show the options - Mathcad has chosen an adaptive algorithm. In this case, the integration can be performed by evaluating this numeric expression. Sometimes, an equation can be simplified before it is evaluated - this gives you greater speed and more precision. The Optimise option tells Mathcad to try this. nextslide © HRS Ltd, 2002.

  18. To designate a set of commands as a program, you use the program line tool The assigned variable takes the value of the last assignment on the program line nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  19. Select part of your document, and choose Insert/Area You can highlight, lock and encrypt your key statements, so your documents are secure Set the properties of the area Choose whether to lock and/or collapse it nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  20. You might think this is a lot to learn. Mathcad is powerful, but it is also intuitive, and comes with many web-based and built-in resources to get you started. You can buy additional Mathcad documents and program extensions,to give you easy access to the world’s knowledge in signal processing,image processing, mechanical design and many other areas nextslide © HRS Ltd, 2002. In NZ phone 0800 477 776, www.hrs.co.nz

  21. Training As with any program, the quickest, easiest, and in the long run cheapest way to learn is to pay a professional trainer to teach you and your staff. HRS has a schedule of open-to-everyone beginner’s Mathcad courses and also runs customised in-house training courses. Contact us for details. nextslide © HRS Ltd, 2002.
