Greek Characters in Mathcad




During my regular Internet research (I spend a portion of my daily work time on listening what is being said in forums, blogs, on Twitter and Facebook about Mathcad and some other PTC products), I just came across this forum question by a student:

“I’m studying computer science and I’m starting to come across a lot of math! I thought it would be fun (yes I really am a geek!) to learn the greek alphabet as it used in mathematics. I was wondering if I should learn the English pronunciation or the Greek?”

This caught my attention and knowing that one of Mathcad’s biggest strengths is its support of standard math notation, I was wondering what this means for Greek characters. While in tools that are code-based, these can cause difficulties, tools like Mathcad should make the use of Greek characters less painful.

I asked my technically well-versed colleagues and learned the following:

Greek symbols as the forum poster mentions are used frequently in maths and science and Mathcad supports the use of Greek symbols so they can be defined and used in calculations.

Greek symbols in Mathcad

As you can see the menu below shows the list of upper and lower case Greek symbols. The tool tip shows the name of the symbol and the shortcut to go from English alphabet to its Greek equivalent.

 

Lowercase and uppercase Greek symbols in Mathcad

The user could just enter h followed by CTRL + G. This will convert the letter h to the Greek symbol Eta.

This is a quick and convenient way to use and familiarize yourself with mapping of English letters to the equivalent Greek symbol.

Further, some Greek letters are pre-defined constants, but Mathcad Prime 1.0 differentiates with the use of labels, to allow use of the same symbol as a constant and also as a variable.

 

Mathcad Prime 1.0 allows use of the same symbol as a constant and also as a variable.

There is no conflict between the use of the symbol as a constant and also as a variable. For example, a related constant is the radiation constant (or radiation density constant) a which is given by:

 

In Mathcad Prime 1.0 there is no conflict between the use of the symbol as a constant and also as a variable.
