The following figure shows the vector with the length \(r = 2\) and the angle \(φ = 45 °\). In the last tutorial about Phasors, we saw that a complex number is represented by a real part and an imaginary part that takes the generalised form of: 1. SonoG tone generator Find more Mathematics widgets in Wolfram|Alpha. Determine the polar form of $\mathcal z_1 = 2 + \mathcal i \sqrt 3$. A 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. Furthermore, the values of elementary complex functions are calculated. Complex numbers in the angle notation or phasor (polar coordinates r, θ) may you write as rLθ where r is magnitude/amplitude/radius, and θ is the angle (phase) in degrees, for example, 5L65 which is the same as 5*cis (65°). Calculation So we can write the polar form of a complex number as: x + y j = r ( cos ⁡ θ + j sin ⁡ θ) \displaystyle {x}+ {y} {j}= {r} {\left ( \cos {\theta}+ {j}\ \sin {\theta}\right)} x+yj = r(cosθ+ j sinθ) r is the absolute value (or modulus) of the complex number. Here, both m and n are real numbers, while i is the imaginary number. \(φ\) is the angle belonging to the vector. \[z = r{{\bf{e}}^{i\,\theta }}\] where \(\theta = \arg z\) and so we can see that, much like the polar form, there are an infinite number of possible exponential forms for a given complex number. Conic Sections Trigonometry. ...
