Although an Arduino may seem somewhat underpowered compared to a computer, it can still process quite complex mathematic work much faster than you can do so with a calculator. There are also examples of people making their own Arduino-powered caluclators, and with this in mind the following library by github user AnonymousPenguin is of interest.
Based on the work published by Arduino enthusiast Oscar Liang, this new library offers faster methods of calculating common trigonometric functions such as sine, cosine, arc cosine and so on. These sorts of functions will not only be useful for academic work but also have practical uses for navigation, autonomous robots and so on.
You can check out the library and download the code from the github page. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
