Hint 1; Complex numbers are not more complicated than any other numbers, just different. Complex number = real number + imaginary number Hint 2; imaginary numbers are not more ethereal than real numbers, just different. Imaginary numbers were invented to solve problems involving square roots of negative numbers. Hint 3; we lied to you when we told you that you cannot take the... read more

Complex Numbers Written by tutor Colin D. How to Envision Complex Numbers Graphically: The Complex Plane The complex number x + yi corresponds to the point with coordinates (x, y) The x-axis is the real axis The y-axis is the imaginary axis Real numbers are associated with points on the x-axis For example:... read more

Complex Numbers In algebra, there are two types of numbers: real numbers and imaginary numbers. Real numbers refer to any ordinary number (e.g. 1, 2, 3 . . .) while imaginary numbers are . . . well . . . imaginary! They don't really exist, they are represented by a real number with the letter i next to it. For example, 3i is an imaginary number. Complex numbers are those consisting... read more
