If the discriminant - the part under the radical sign in the quadratic formula - is negative, then the result is complex, it is as simple as that. You can't convert a complex number to a real number. If a particular problem requires only real-number solutions, then - if the formula gives complex numbers - you can state that there is no solution.
Adjoint operator of a complex number?
You get a complex number unless the real number happens to be 0 or 1.
The absolute value of a complex number is the magnitude of the number, which is found from sqrt(aÂ² + bÂ²) for the complex number a + bi
Yes. And since Real numbers are a subset of complex numbers, a complex number can also be a pure real.Another AnswerYes, for example: (0 + j5) is a complex number, whose 'real' number is zero.
The imaginary part of the complex number –5 + 3i is
No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.
Graphically, the conjugate of a complex number is its reflection on the real axis.
One is a complex number and a real number.
Any real number is a complex number with an imaginary part equal to 0
When a complex number is multiplied by its conjugate, the product is a real number and the imaginary number disappears.
