a number of the form a+bi where a and b are real numbers and i is the square root of -1
Any number of the form a + bi, where a and b are real numbers and i is an imaginary number whose square equals -1. Any number consisting of both real numbers and imaginary numbers. It has the form a + bi, where a and b are real numbers and i = SquareRoot(-1); a is called the real part and bi the imaginary part. Because a or b can equal 0, any real or imaginary number is also a complex number. Invented as an extension of the real numbers so that certain algebraic equations such as x^2 + 1 = 0 would have solutions, the complex numbers form an algebraic field, meaning that they obey the commutative law and the associative law (with respect to addition and multiplication), as well as certain other rules in much the same way real numbers do (see field theory)
A number consisting of an ordered pair of real numbers, expressible in the form a+bi, where a and b are real numbers and i squared equals -1
The sum of a real number and an imaginary number is called a complex number (See also number and imaginary number ) Examples: 1 + i, -3 + 2i, -3 7 - i are complex numbers
A complex number is made up of two parts: a real part and an imaginary part A complex number can be represented by an ordered pair (a, b ), where a is the value of the real part and b is the value of the imaginary part The same complex number could also be represented as a + bi, where i is the square root of -1
A number of the form a + bi where a and b are real numbers and i is the square root of -1
number which is a combination of real and imaginary numbers, non-concrete numbers (Mathematics)
A complex number is two-dimensional and can be placed on a number plane defined by a real number axis (horizontal) and an imaginary number axis (vertical) It can also be written in the form a + bi, where a represents the position along the real axis, while b represents the position along the imaginary axis Learn more about real and complex numbers at Cut the Knot
