## What is a rectangular equation?

A rectangular equation, or an equation in rectangular form is an equation composed of variables like x and y which can be graphed on a regular Cartesian plane. For example y=4x+3 is a rectangular equation.

## What is Polar form equation?

The polar form of a complex number z=a+bi is z=r(cosθ+isinθ) , where r=|z|=√a2+b2 , a=rcosθ and b=rsinθ , and θ=tan−1(ba) for a>0 and θ=tan−1(ba)+π or θ=tan−1(ba)+180° for a<0 . Example: Express the complex number in polar form. 5+2i. The polar form of a complex number z=a+bi is z=r(cosθ+isinθ) .

## What is polar equation?

Polar Equations A polar equation is any equation that describes a relation between r r r and θ theta θ, where r r r represents the distance from the pole (origin) to a point on a curve, and θ theta θ represents the counterclockwise angle made by a point on a curve, the pole, and the positive x x x-axis.

## How do you do polar coordinates on a calculator?

Enter the number or expression, then ►Rect . To convert an answer to polar form: Enter the number or expression, then ►Polar . The calculator will display the angle (part of the exponent on e) in radians or degrees according to how you set the mode.

## What is rectangular and polar form?

In Rectangular Form a complex number is represented by a point in space on the complex plane. In Polar Form a complex number is represented by a line whose length is the amplitude and by the phase angle.

## How do you divide polar form?

To multiply complex numbers in polar form, multiply the magnitudes and add the angles. To divide, divide the magnitudes and subtract one angle from the other.

## How do you convert from Polar to Rectangular?

To convert from polar coordinates to rectangular coordinates, use the formulas x=rcosθ and y=rsinθ.

## How do you convert rectangular form to polar form?

Converting from Polar Form to Rectangular Form To convert from polar to rectangular, find the real component by multiplying the polar magnitude by the cosine of the angle, and the imaginary component by multiplying the polar magnitude by the sine of the angle.

## Are Cartesian and rectangular coordinates the same?

The Cartesian coordinates (also called rectangular coordinates) of a point are a pair of numbers (in two-dimensions) or a triplet of numbers (in three-dimensions) that specified signed distances from the coordinate axis.
