The square root of -1 is not NaN (anymore) Up until the previous version, attempting to calculate the square root of a negative number would have resulted in Alcula’s scientific calculator returning ‘NaN’ as a solution. NaN is not a number, infact, NaN stands for ‘Not A Number’....
Here’s a quick rundown of the individual complex number forms and their coordinates: FormRectangularPolar Algebraic z = x + yj - Geometric z = (x, y) z = (r,φ) Trigonometric z = |z|(cos(x/|z|) + jsin(y/|z|)) z = r(cos(φ) + jsin(φ)) Exponential z = |z|eatan2...
The "unit" imaginary number (like 1 for Real Numbers) is i, which is the square root of −1 When we square i we get −1 i2 = −1 Examples of Imaginary Numbers: 3i 1.04i −2.8i 3i/4 (√2)i 1998i And we keep that little "i" there to remind us we still need to ...
This calculator converts a complex number from rectangular form (a+bi)(a+bi) into polar form (r∠θorr(cos θ+i sin θ))(r∠θorr(cos θ+i sin θ)). It’s useful for students, engineers, and anyone working with complex numbers in electrical engineering or mathematics....

complex number (mathematics) A number of the form x+iy where i is the square root of -1, and x and y are real numbers, known as the "real" and "imaginary" part. Complex numbers can be plotted as points on a two-dimensional plane, known as anArgand diagram, where x and y are ...
Particularly useful in this regard is the theory of Sturm sequences, which can be used to determine the number of real roots in a prescribed interval. Finally, for every polynomial, a matrix can be found that has the same characteristic polynomial; thus, the problem of finding roots of a ...
