The current mathematical calculators do not
have the capabilities that the engineering and scientific communities need.
They stand in high demand for a new style calculator. The new calculator like radical’s calculator should not be
just a mathematical calculator it should have additional capabilities that make
it stand a head in competition with the
most sophisticated mathematical platforms. It should care for the complexity of the problems that face
engineers.

First,
the radical’s calculator has a powerful underlying mathematical engine. It can
do many operations in matrices, algebra, differentiation, integration, plot
graphs and scientific calculations.

In algebra, the inputs and outputs should be
in a symbolic format, and it should do the operations of add, multiply, subtract,
and divide algebraically. Now one can have his
tool that does the long algebraic
division for him. It also should do
factorization and finds roots in addition to algebraic differentiation and
integration.

It should allow the user to enter
mathematical expressions the same way he is used
to in school and university. It should support brackets and nested brackets to
any level and support exponential, logarithmic, and trigonometric functions and
the brackets of these functions can contain functions This way any function can
be expressed for scientific calculations,
plot graphs or calculus.

Now imagine an engineer who wants to solve a
design problem to take some decision. The problem can be solved by multiplying
matrix A with the inverse of matrix B and adding that to that the result of
matrix B multiplied with the inverse of matrix A. The normal matrix calculator
would not do to solve this problem. However; this calculator should give the
user the appropriate tools to solve such problem. The user can declare three
matrices internally and manipulate them to do a sequence of matrix operations
on data and follow up on the display screen the progress of operations to reach
the answer. This is usually done with
sophisticated mathematical platforms that are usually very expensive but never
with any calculator. One should be able
to do all these sophisticated functionalities just by pressing buttons and not
by writing code like the other programs demand.

This way the user can do a continuous set of operations on data and follow
that on the display screen to solve his design or research problems.

The algebra section of the radical’s calculator

**has the same capabilities. Imagine a design problems demands solving several algebraic fractions. To do this by hand is extremely time consuming and error prone and when one has many of these problems it becomes impossible to do. The programs that can help in doing that demand that the user write substantial bits of code using their platform's mathematical engine but with this new calculator, it should be very easy to solve this problem. The user should be able to do it in minutes and with absolutely no programming. The calculator is simple to use to carry out the calculations with approximate results.**
This significantly
improves the user experience of engineers and scientists!
