The rectangular coordinates will be (x=7cot(θ), y=7).
<h3>What are polar coordinates?</h3>
A pair of coordinates locating the position of a point in a plane, the first being the length of the straight line ( r ) connecting the point to the origin, and the second the angle ( θ ) made by this line with a fixed line.
We have the standard conversion toolbox:
![x=rcos(\theta)\\\\y=rsin(\theta)](https://tex.z-dn.net/?f=x%3Drcos%28%5Ctheta%29%5C%5C%5C%5Cy%3Drsin%28%5Ctheta%29)
Here it is given that
![r=7cosec(\theta)](https://tex.z-dn.net/?f=r%3D7cosec%28%5Ctheta%29)
so
![x=7cosec(\theta)\times cos(\theta)=\dfrac{7cos(\theta)}{sin(\theta )}=7cot(\theta)\\\\\\y=7cosec(\theta)\times sin(\theta)=\dfrac{7sin(\theta)}{sin(\theta)} = 7](https://tex.z-dn.net/?f=x%3D7cosec%28%5Ctheta%29%5Ctimes%20cos%28%5Ctheta%29%3D%5Cdfrac%7B7cos%28%5Ctheta%29%7D%7Bsin%28%5Ctheta%20%29%7D%3D7cot%28%5Ctheta%29%5C%5C%5C%5C%5C%5Cy%3D7cosec%28%5Ctheta%29%5Ctimes%20sin%28%5Ctheta%29%3D%5Cdfrac%7B7sin%28%5Ctheta%29%7D%7Bsin%28%5Ctheta%29%7D%20%3D%207)
therefore the rectangular coordinates are (7cot(θ), 7)
