WebImaginary numbers are used to help us work with numbers that involve taking the square root of a negative number. In this tutorial, you'll be introduced to imaginary numbers and learn that they're a type of complex number. How can you use trigonometry to represent complex numbers?
WebA complex number is the sum of a real number and an imaginary number. A complex number is expressed in standard form when written \,a+bi\, where \,a\, is the real part and \,b\, is the imaginary part. For example, \,5+2i\, is a complex number. So, too, is \,3+4i\sqrt {3}. Imaginary numbers differ from real numbers in that a squared imaginary ...
