Mathematica is a computational, mathematics, tool.  It is shipped free with Raspberry Pi. In this blog entry, we will look at some basic functions to get you started quick on the subject. To fire up Mathematica on Raspberry Pi, either click on the Mathematica icon or on the Wolfram icon for command line interface (see … Continue reading Introduction to Wolfram Mathematica

## Jacobsthal Number Sequence

In Mathematics several well-known sequences exist, like Fibonacci, Square numbers sequence, etc. One such sequence is Jacobsthal, which states that: Another way to calculate the Jacobsthal number without using recursion on the Jacobsthal equation, is to use the Binet formula [4][5]: Using any of the forumalas above to generate the first 50 numbers in the … Continue reading Jacobsthal Number Sequence

## Understanding Mathematical Symbols – Summation (Addition)

When a summation over a range of numbers is to be presented it is not uncommon to shorthand the notation using the Sigma (the letter S in Greek, written as a Big E with the middle t replaced by a less than symbol ). For example, the following sums can be represented in the Sigma … Continue reading Understanding Mathematical Symbols – Summation (Addition)

## Arithmetic Mean

Arithmetic Mean is one of the most common ways of calculating a sample’s average. The method of calculating the Arithmetic Mean is to sum the values in the sample set and divide the result by the sample size. In Mathematical Notation this is written as: The mathematical formula above with the sample examples can be … Continue reading Arithmetic Mean
