[tex]18=rcos \theta[/tex]

[tex]\frac{\ 18}{cos \theta}= \sqrt{x^2+y^2}[/tex]

how do I get rid of the cosine?

In summary, a simple polar to cartesian conversion is a mathematical process that transforms coordinates from a polar coordinate system to a cartesian coordinate system. Polar coordinates are a way of representing points in a two-dimensional plane using a distance (r) from the origin and an angle (θ) from a reference line. Cartesian coordinates are a way of representing points in a two-dimensional plane using horizontal (x) and vertical (y) distances from a fixed point called the origin. To convert from polar to cartesian coordinates, you can use the formulas x = r * cos(θ) and y = r * sin(θ), where r is the distance from the origin and θ is the angle from the reference line. This conversion is useful for plotting and analyzing

x=18 is the solution. I can't believe it.

A simple polar to cartesian conversion is a mathematical process that transforms coordinates from a polar coordinate system to a cartesian coordinate system.

Polar coordinates are a way of representing points in a two-dimensional plane using a distance (r) from the origin and an angle (θ) from a reference line.

Cartesian coordinates are a way of representing points in a two-dimensional plane using horizontal (x) and vertical (y) distances from a fixed point called the origin.

To convert from polar to cartesian 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 reference line.

Polar to cartesian conversion is useful because it allows us to easily plot and analyze data that is given in polar coordinates. It also allows us to easily transform and manipulate coordinates to solve mathematical problems.
