WebMar 26, 2016 · Entering complex numbers on the TI-84 Plus. You can enter an expression that includes the imaginary number, i, by pressing [2nd] [.]. Somewhere along the way, you have probably learned that i2 = –1. Interestingly enough, your calculator not only knows that i2 = –1, but automatically simplifies any result that would have had i2 in it. WebA complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i 2 = −1.For example, 2 + 3i is a complex number. This way, a complex number is defined as a …

Web1 Review of Complex Numbers Complex numbers can be written as z= a+bi, where aand bare real numbers, and i= p 1. This form, a+ bi, is called the standard form of a complex number. When graphing these, we can represent them on a coordinate plane called the complex plane. It is a lot like the x-y-plane, but the horizontal axis represents the real ... WebWe can plot such a number on the complex plane (the real numbers go left-right, and the imaginary numbers go up-down): Here we show the number 0.45 + 0.89 i Which is the same as e 1.1i. Let's plot some more! A Circle! Yes, putting Euler's Formula on that graph produces a circle: e ix produces a circle of radius 1
