## 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) :

- x = r × cos( θ )
- 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).
