An imaginary number is any real number multiplied by the square root of negative one (-1). This may be restated in other terms for simplification. Imaginary Number ComponentĪn imaginary number is defined as any number that when squared results in a real negative number. In the expression a + bi, a is the real number component. Math tutoring is an excellent way to help students understand complex conjugates as they’re also necessary for finding the amplitude of the polar form of a complex number.Įvery complex number possesses a real number component added to an imaginary component. In terms of their mathematical applications, complex conjugates are used in the rationalization of complex numbers. The use of complex conjugates works despite the presence of imaginary components, because when the two components are multiplied together, the result is a real number. A complex number can be represented by the expression a + bi, and its complex conjugate can be represented by a - bi, where a and b are real numbers and i is an imaginary number (specifically, the square root of negative 1).ĭespite having imaginary components, complex conjugates are used to describe physical realities. This complex conjugate will have the same real part, while the imaginary part will have the same magnitude but the opposite sign. In mathematics, every complex number (a two-component number involving a real number added to an imaginary number) has a complex conjugate. Our audiences’ needs are always our top priority.
