The Mathcad Virtual Conference – Worth a Visit?
I’d clearly say YES! And I don’t do this because it is my job as a marketer to promote this event. I think every user has individual needs and expectations, but we have talked to many of you and taken your feedback from last year’s event and considered this when planning the Mathcad Virtual Conference 2011. So what is the …

On a Mile High Mathcad Mission at ICTCM
I recently returned to Needham from the International Conference on Technology in Collegiate Mathematics (ICTCM) in Denver, CO. ICTCM is a modest-sized conference for mathematics educators. The attendees are all passionate about teaching collegiate mathematics and curious about the ways that their colleagues employ technology to increase student achievement in the early years of collegiate mathematics. This year, the PTC …
Mathcad A-Z: E is for Excel
Did you know that there are many ways to import data from Excel to Mathcad? In Mathcad 15 and earlier versions, you can use the Excel Component or Data Import Wizard to import data. The data can then be embedded in your worksheet, so that you can edit the data directly in Mathcad. Use Mathcad to analyze and visualize the …
Show Your Calculation Skills with Mathcad – And Win!
Today is Friday and thus time to use Mathcad for some less serious problems than calculating open channel flow, voltage drops across circuits, or the transmission gear ratio for a geared drive. Less serious? Well, some of the insects coming to life in springtime and summer may turn into a serious problem to some of us. Believe me, I have …

Mathcad A to Z: D is for Design of Experiments
Design of Experiments (DOE) also known as experimental design is a method of investigation, used when there are a number of factors and variations. The DOE functions allow you to sort which among a large group of factors have the most influence on the result. New DOE Functions: We’ve added 28 new Design of Experiments (DOE) functions to Mathcad 15.0 and Mathcad Prime …
Bees and Social Product Development…Really!
I had the great fortune this past weekend to attend a lecture given by Cornell’s Dr. Thomas D. Seeley on decision-making in honeybees. While I am very interested in the bees (yes I am), I couldn’t help but to let me mind wander to comparisons of human behavior. So what does honeybee decision-making have to do with product development? I …
Creating eUnits (or eBooks) for Your Course (or Lab) with Mathcad
From time to time I play around with ideas for using Mathcad as a curriculum development tool. Mathcad has and continues to have many capabilities for writing lessons, generating quizzes, and completing homework assignments. For both teachers and students Mathcad’s standard mathematics notation, plotting tools, word processing capabilities, and data management with units offer a powerful toolkit for math, science, …

I Stumbled Upon Some Math Today…
… and I recently stumbled upon a blog with this very tagline — the Math Encounters Blog by Mark Biegert. It’s full of stories of everyday math – such as “Magic Number Analysis – ‘Money Factor’ in Auto Leasing” or “Designing a stairway for my cabin” – and many of them involve Mathcad. Of course, I immediately thought of pulling …
Mathcad A-Z: C is for Curve Fitting
Curve fitting means finding a mathematical function or plot curve that best fits a set of data. By doing so, you can see patterns in a data set, predict future data points, and understand the relationship between different factors. Mathcad has a number of specialized curve-fitting functions. A least squares fit is the method most commonly used to find the …
Solving Systems of Equations through Mathcad Solve Blocks, part 2
Sometimes solve blocks cannot find a solution. Read on to see how to resolve some issues. Errors and Problems with No Solutions Sometimes there might be no solution, or Mathcad might not find a solution. In either case, Find displays the error message “No solution was found.” The problem asks for numbers u and v that add to both 2 and 3, …
