# How do you find polar coordinates from rectangular coordinates on a calculator?

## How do you find polar coordinates from rectangular coordinates on a calculator?

To convert from rectangular coordinates to polar coordinates, use one or more of the formulas: cosθ=xr, sinθ=yr, tanθ=yx, and r=√x2+y2.

How do you find the polar coordinates of a point calculator?

To find the polar coordinates of a given point, you first have to draw a line joining it with the pole. Then, the point’s coordinates are the length of this line r and the angle θ it makes with the polar axis. Our polar coordinates calculator is able to convert between Cartesian and polar coordinates.

Is cartesian form same as rectangular form?

Cartesian form and rectangular form are two different names for the same system. A complex number “z = a + bi” form is called cartesian form or rectangular form.

### 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 you convert polar to cartesian?

To convert from Polar Coordinates (r,θ) to Cartesian Coordinates (x,y) :

1. x = r × cos( θ )
2. y = r × sin( θ )

What is the polar form of Cartesian coordinates?

Summary. To convert from Polar Coordinates (r,θ) to Cartesian Coordinates (x,y) : x = r × cos( θ ) y = r × sin( θ )

## Is Cartesian form same as rectangular form?

How do you convert polar to Cartesian form?

What is the formula for polar?

Plotting in Polar. A polar function is an equation of the form r = f(θ). For every θ-value in the domain of f, you find the corresponding r-value by plugging θ into the function. It’s really the same idea as plugging in various x-values into a typical ( Cartesian ) function to find the y-values.

### What is the polar coordinate equation?

Graphing in Polar Coordinates. A typical polar equation is in the form r = f (θ), where f is some function ( of θ). θ is the independent variable, and r is the dependent variable.

How do you find the polar coordinates of a point?

To find the polar coordinates of a given point, you first have to draw a line joining it with the pole. Then, the point’s coordinates are the length of this line r and the angle θ it makes with the polar axis.

How do you convert rectangular to polar coordinates?

To convert from rectangular coordinates (x,y) to polar coordinates (r, θ), the following equations should be used: r = sqrt( x^2 + y^2) θ = tan^-1 (y/x) Substituting (-3,3) accordingly to the equations, we obtain r equal to 3*sqrt(2) and θ equal to -π/4. Thus, the polar coordinates equivalent to (-3,3) is (3*sqrt(2), -π/4).
