Web10 I know that a sinusoidal plane wave can be represented by the wave equation ψ ( x, t) = A cos ( k x − ω t) I have also seen that a plane wave can be represented in complex exponential form as ψ ( x, t) = A e i ( k x − ω t) I know that the Euler Formula is e i … WebExponential representation of a complex number. In exponential form, a complex number z is represented as: \[\bbox[#FFFF9D]{z=r \cdot e^{i \cdot \varphi}}\] Where the …
Webcomplex number, but it’s also an exponential and so it has to obey all the rules for the exponentials. In particular, eiφ1eiφ2 = ei(φ1+φ2) (2.76) eiφ1 eiφ2 = ei(φ1−φ2). (2.77) You see that the variable φ behaves just like the angle θ in the geometrial representation of complex numbers. Furthermore, if we take the complex WebThere are two different complex numbers plotted on the coordinate system, z and jz. We defined z to be z = a + jb. Then we asked "If (a + jb) is the value of z, what is the value of j time z?" An expression for jz is worked out on the left side of the screen. It turned out, jz = -b + ja. This is shown on the plot, too.
WebThe answer is a combination of a Real and an Imaginary Number, which together is called a Complex Number. We 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 e1.1i Let's plot some more!
