The trip of the cubic equation

The trip of the cubic equation

There is an important question

Was there mathematics now, information we use, that was previously classified?

In fact, in the past it was classified mathematical information and nobody should know it

This topic is included in a famous storyTHE TRIP OF THE CUBIC EQUATION, which is one of the stories concealing mathematical discoveries

The journey began in the 16th century, when the Italian mathematician SCIPIONE DEL FERRO came up with a solution CUBIC EQUATION.

The important thing here is that Scientist has suppressed this solution and has not published it.In that era, the solution of DEL FERRO was a very great achievement because no one could solve that equation. Until that DEL FERRO gave that proof to his student ANTONIO FIOR when he was on his deathbed. ANTONIO FIOR also concealed and muted that solution to always outperform other mathematician

So were the so-called MATH DUELS. Every mathematician was challenging another mathematician . Each of them gives the other equations and issues. Who can solve the most number of issues is the winner

Everyone trying to challenge FIOR was losing. Because FIOR is the only one known to solve this type of equation

It remained as it was until a scientist named NICOLO TARTAGLIA came up and challenged FIOR

TARTAGLIA was able to guess what form of equations FIOR could solve, so TARTAGLIA gave FIOR equations he was sure that FIOR would not be able to solve, even though he also did not know their solution, and even FIOR gave TARTAGLIA equations.

It took TARTAGLIA 40 days trying to solve those equations and issues until he managed to reach a solution stronger than the FIOR solution and solve all the problems, in return FIOR could not solve any of the issues given to him by TARTAGLIA

And here TARTAGLIA is very famous for being able to beat FIOR,And also until TARTAGLIA concealed the secret of solving these equations

The Italian Mathematics all spoke and asked TARTAGLIA to know how to solve, but he refused

But one of them decided that he would not give up his name GEROLANO CARDANO who requested and sent messages to TARTAGLIA too many and begged him, but TARTAGLIA was always refusing.

But Cardano had a smart idea, so he sent out a number of equations and TARTAGLIA solved it and Cardano guesses the solution, but even this idea was rejected by TARTAGLIA

But after many attempts that CARDANO repeated, TARTAGLIA agreed and decided to give him the secret to solving these equations but on the condition that they have a contract in order to ensure that CARDANO will keep the secret between them, CARDANO agreed and sat a year to understand how TARTAGLIA discovered this solution

Until CARDANO reached the development of the solution and was able to develop a more comprehensive solution than the TARTAGLIA solution,

However, the solution that CARDANO reached was through the solution of TARTAGLIA and therefore could not publish that solution

Until the year 1953 when CARDANO traveled to the Italian city of POLONIA, in which the original books of DEL FERRO were the first one to arrive at a solution, and CARDANO discovered that DEL FERRO had discovered the solution of the equation before everyone, and thus the contract between him and TARTAGLIA became invalid.

CARDANO published what he knew about the cubic equation in his book THE CREAT ATR OR THE RULES OF ALGEBRA

The importance of the cubic equation and its solution.

We use the solution of the cubic equation in computers in Bézier curves to put drawings and curves, and use it in thermodynamics to calculate the pressure and temperature in the oil and gas industries.

We use the solution of the cubic equation to calculate the Aerodynamics friction force and the required velocity for flight. Often without solving the cubic equation there will be no planes

That is how the journey ends. Thanks for the good follower.
