## How do you put a polar equation into a calculator?

The radian symbol (r) can be found in the Angle menu. So to enter, for example, the polar form number (240∠75) into the calculator you must enter 240 e^(i 75/1r). The calculator will then display 62.12 + 231.8i corresponding to the polar form number (240∠75).

## What is 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.

## 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 polar to Complex?

A complex number z in polar form is given as r(cosθ+isinθ) and is often abbreviated as rcisθ, where r equals the modulus of the complex number. The value θ is called the argument of z, denoted by arg(z). Note that r(cos(θ+2kπ)+isin(θ+2kπ)) represents the same complex number for every integer k.

## How do you convert Polar to Rectangular?

Summary: to convert from Cartesian Coordinates (x,y) to Polar Coordinates (r,θ):r = √ ( x2 + y2 )θ = tan1 ( y / x )
