#### Rectangular equation

## What is rectangular form?

In the rectangular form, a complex number can be represented as a point on a two dimensional plane called the complex or s-plane. So for example, Z = 6 + j4 represents a single point whose coordinates represent 6 on the horizontal real axis and 4 on the vertical imaginary axis as shown.

## How do you divide a rectangular form?

1.4 Division: Rectangular Form The trick is to multiply by the number 1, in a special form that simplifies the denominator to be a real number and turns division into multiplication. You should try this by writing out the real an imaginary components separately.

## Is Cartesian form same as rectangular form?

Rectangular coordinates, or cartesian coordinates, come in the form (x,y). Polar coordinates, on the other hand, come in the form (r,θ). Instead of moving out from the origin using horizontal and vertical lines, we instead pick the angle θ, which is the direction, and then move out from the origin a certain distance r.

## What is Cartesian equation?

: an equation of a curve or surface in which the variables are the Cartesian coordinates of a point on the curve or surface.

## What is T in parametric equations?

The variable t is called a parameter and the relations between x, y and t are called parametric equations. The set D is called the domain of f and g and it is the set of values t takes. Conversely, given a pair of parametric equations with parameter t, the set of points (f(t), g(t)) form a curve in the plane.

## What are parameters in math?

Parameter, in mathematics, a variable for which the range of possible values identifies a collection of distinct cases in a problem. The general equation of a straight line in slope-intercept form, y = mx + b, in which m and b are parameters, is an example of a parametric equation.

## What is the parametric equation of a straight line?

And this is the parametric form of the equation of a straight line: x = x_{1} + rcosθ, y = y_{1} + rsinθ.
