# Write a quadratic equation with imaginary numbers i

Like understanding emost explanations fell into one of two categories: Just wait until college.

But then people researched them more and discovered they were actually useful and important because they filled a gap in mathematics And that is also how the name " Real Numbers " came about real is not imaginary. Yep, Complex Numbers are used to calculate them! Using something called "Fourier Transforms".

In fact many clever things can be done with sound using Complex Numbers, like filtering out sounds, hearing whispers in a crowd and so on.

It is part of a subject called "Signal Processing". When we combine two AC currents they may not match properly, and it can be very hard to figure out the new current. But using complex numbers makes it a lot easier to do the calculations.

And the result may have "Imaginary" current, but it can still hurt you! The beautiful Mandelbrot Set part of it is pictured here is based on Complex Numbers.

Quadratic Equation The Quadratic Equationwhich has many uses, can give results that include imaginary numbers Also Science, Quantum mechanics and Relativity use complex numbers. It "cycles" through 4 different values each time we multiply:This calculator does basic arithmetic on complex numbers and evaluates expressions in the set of complex numbers.

As imaginary unit use i or j (in electrical engineering) which satisfies basic equation i 2 = −1 or j 2 = −regardbouddhiste.com calculator provides also a conversion of complex number into goniometric exponential or polar coordinates.

A much simpler function that uses a single input line without prompts and returns the answer to the home screen instead of program/io. How to use: type “qa(a,b,c)” into the home screen command line where a b and c are the respective coefficients after you have created the function below.
