Polar Form Calculation Formula
To find the polar form of a complex number, we use the following formulas:
r = sqrt(a^2 + b^2)
theta = atan(b / a)
In these formulas, r represents the magnitude and theta signifies the angle in radians.
Categories of Polar Form Calculations
To better understand the results of our polar form calculations, we can categorize them into the following ranges:
| Category | Range | Interpretation |
|---|---|---|
| Small | 0-1 | Low magnitude |
| Medium | 1-10 | Moderate magnitude |
| Large | 10+ | High magnitude |
Polar Form Calculation Examples
Let’s take a look at how our favorite action hero would fare in a polar form calculation:
| Name | Complex number | Polar form | Calculation |
|---|---|---|---|
| Indiana Jones | 3 + 4i | 5 ∠ 53.13° | sqrt(3^2 + 4^2) = 5, atan(4 / 3) = 53.13° |
Calculation Methods
There are various ways to calculate the polar form of a complex number. Here are a couple of them:
| Method | Advantages | Disadvantages | Accuracy |
|---|---|---|---|
| Direct | Simple | Limited to basic problems | Moderate |
