The Leap Forward

We are very proud to present you the new MathistIt is a real sneak peak into the future, that allows you to easily solve and compute anything you write with a single click!

Here are some examples;

• Simplify any expression to speed up problem solving,
• Plot graphs,
• Evaluate expressions and get approximate values,
• Solve equations and inequalities (with visual representation),
• Solve definite and indefinite integrals (with visual representation),
• Crunch difficult logarithms,
• Find derivatives and much more…

You can do all of this with just one button: Why is this important?

Have you ever worked on a problem, that is easy to understand, but just requires too much number crunching? – So did we!

We understand that learning a million new things every day as a technology or a science student doesn’t leave too much time for crunching math. And yet in most cases you cannot solve anything without it.

We decided create a solution to this problem with the help of cutting-edge technology.

The Mathist allows you to focus on problem solving and not number crunching, so that you achieve better results at things you are interested in!

## Ho ho ho, Merry Christmas! :) Me and my team wish you the nicest holidays ever! Be prepared to recieve some nice gifts from us in the next few days! 🙂

Sincerely, The Mathist team

p.s. We at The Mathist really love to express our thoughts with these creative math notes… 🙂

## Feeling Lucky? – Total Probability Theory When Blaise Pascal and Pierre de Fermat studied a problem related to a gambling game they developed what is now widely known as the probability theory.

They were hired by two very rich man, that were interrupted in a middle of a gambling game, to determine in which proportion the stakes should be divided based on the current score.

The formula of total probability is widely used and is very significant in the probability theory.

The fun fact is that the interest in probability was solely influenced by gambling games throughout the 17. 18.  and 19. century. Only way later was probability studied for theoretical reasons. ## The Most Beautiful Formula

The famous Euler’s identity is  widely considered the most beautiful formula in all of maths.

For me It is because it binds all of the fundamental mathematical constants in a single,  short and sweet equality.

• The number e, which is the base of the natural logarithm,
• The number pi, which represents the ratio between the, circumference and the diameter of a circle
• The constant i, or the famous imaginary unit, defined as the square root of -1,
• The constant 0, which is the neutral element for the operation of addition,
• The constant 1, which is the neutral element for the operation of multiplication.

Thank you, sir Euler! 🙂

## The Famous Harmonic Series

The divergence of the harmonic series is the source of many counterintuitive conclusions, such as this one:

Given a collection of identical dominoes, it is clearly possible to stack them at the edge of a table so that they hang over the edge of the table without falling. The fun fact is that one can stack them in such a way to make the overhang arbitrarily large, provided there are enough dominoes. 🙂

## The New Autocomplete Feature!

With thie new Autocomplete feature it is now easier than ever to write formulas!

To write a formula just start typing its name and The Mathist will suggest it to you.

Using the Up and Down keys choose the formula from the list and insert it by pressing the Right arrow or the Enter key, or just tap or click on the one you need.

For example: to write the root, start typing: ro… and watch The Mathist narrow the choices with each letter. 🙂

To cancel the autocomplete, press Escape or the Left arrow.
