### How do you convert from polar coordinates to rectangular coordinates?

## How do you convert from polar coordinates to rectangular coordinates?

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

- r = √ ( x2 + y2 )
- θ = tan-1 ( y / x )

### Which of the following is a rectangular equation of the polar equation?

To convert from polar coordinates to rectangular coordinates, use the formulas x=rcosθ and y=rsinθ. See Example 10.3. 3 and Example 10.3. 4.

**What is the difference between rectangular and polar coordinates?**

Rectangular coordinates, or cartesian coordinates, come in the form (x,y). Polar coordinates, on the other hand, come in the form (r,θ). Instead of moving out from the origin using horizontal and vertical lines, we instead pick the angle θ, which is the direction, and then move out from the origin a certain distance r.

**How do you convert to rectangular coordinates?**

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

## How to convert a rectangular number to a polar number?

Rectangular forms of numbers can be converted into their polar form equivalents by the formula, Polar amplitude= √ x 2 + y 2, where x and y represent the real and imaginary numbers of the expression in rectangular form.

### How can I change the precision of my Polar calculator?

You can change the precision of all the calculations by changing the “Decimal places” option. Go back to the examples on the Polar Form page and try them here in the calculator, and compare the results.

**How do you change the radius of a circle in polar?**

You can also drag point P to change the radius of the circle, and/or the angle to your desired values. You can zoom the graph in or out using the navigation icons at the bottom of the graph, and pan left-right, up-down by holding down the key while dragging the graph.

**How to find the amplitude of a rectangular number?**

Rectangular forms of numbers can be converted into their polar form equivalents by the formula, Polar amplitude= √ x 2 + y 2, where x and y represent the real and imaginary numbers of the expression in rectangular form. This finds the amplitude of the polar expression.
