As physicists, mathematicians or engineers, we are all involved with mathematical calculations in our everyday work. Most of the laborious, complicated, and time-consuming calculations have to be done over and over again if we want to check the validity of our assumptions and derive new phenomena from changing models. Even in the age of computers, we often use paper and pencil to do our calculations. However, computer programs like Maihemaiicu have revolutionized our working methods. Mulhemulicu not only supports popular numerical calculations but also enables us to do exact analytical calculations by computer. Once we know the analytical representations of physical phenomena, we are able to use Mulhemuiica Ю create graphical representations of these relations. Days of calculations by hand have shrunk to minutes by using Maihemaiicu. Results can be verified within a few seconds, a task that took hours if not days in the past.
