## 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 )

## 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 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 and rectangular 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.

## 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.

## How do polar coordinates work?

The polar coordinates of a point describe its position in terms of a distance from a fixed point (the origin) and an angle measured from a fixed direction which, interestingly, is not “north” (or up on a page) but “east” (to the right). That is in the direction Ox on Cartesian axes.

## What is polar angle?

In the plane, the polar angle is the counterclockwise angle from the x-axis at which a point in the. -plane lies. In spherical coordinates, the polar angle is the angle measured from the -axis, denoted. in this work, and also variously known as the zenith angle and colatitude.

## 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 complex numbers to polar form?

To write complex numbers in polar form, we use the formulas x = r cos θ , y = r sin θ displaystyle x=rcos theta ,y=rsin theta x=rcosθ,y=rsinθ, and r = x 2 + y 2 displaystyle r=sqrt{{x}^{2}+{y}^{2}} r=√​x2​+y2​​​​.

#### Depreciation equation

What are the 3 depreciation methods? There are three methods for depreciation: straight line, declining balance, sum-of-the-years’ digits, and units of production. What do you mean by depreciation? Definition: The monetary value of an asset decreases over time due to use, wear and tear or obsolescence. This decrease is measured as depreciation. How do you […]
