Polar to rectangular

$$r=1-2 \sin\left({\theta}\right)$$

$${x}^{2}+{y}^{2}=\sqrt{{x}^{2}+{y}^{2 }}+2y$$

Is this an answer just hard to get $y=$

You've made a minor sign slip, but think of the graph of the polar equation...would you expect to get $y$ as a function of $x$?

$${x}^{2}+{y}^{2}=\sqrt{{x}^{2}+{y}^{2 }}-2y$$

So this is the final

Yes, that looks good to me. :D
 

FAQ: Find Solution for Polar to Rectangular Equation

1. What is a polar to rectangular equation?

A polar to rectangular equation is a mathematical representation that allows you to convert coordinates from polar form (r, θ) to rectangular form (x, y). This is useful for working with geometric shapes and solving equations.

2. How do I convert from polar to rectangular coordinates?

To convert from polar to rectangular coordinates, you can use the following formulas:
x = r cos(θ)
y = r sin(θ)
Where r is the distance from the origin and θ is the angle from the positive x-axis to the point.

3. What is the purpose of converting from polar to rectangular coordinates?

Converting from polar to rectangular coordinates can make it easier to graph and solve equations involving geometric shapes. It can also help with visualizing and understanding the relationship between polar and rectangular coordinates.

4. Can I convert from rectangular to polar coordinates?

Yes, you can also convert from rectangular to polar coordinates using the following formulas:
r = √(x^2 + y^2)
θ = tan^-1(y/x)
Where x and y are coordinates in rectangular form.

5. Are there any limitations to using polar to rectangular equations?

One limitation of using polar to rectangular equations is that they are not suitable for all types of equations. They are most commonly used for equations involving circles, ellipses, and other geometric shapes. Additionally, they may not be the most efficient way to solve certain equations, so it's important to consider alternative methods as well.
