From what I know, the x-coordinates can be written as r.*cos(t) and y-coordinates as r.*sin(t). However, when it comes to plotting, I have no idea of how I shall do. I've tried to plot this function in plotting softwares, such as geogebra and know what it is supposed to look like.

My current script looks like this
As you can see, I'm still hesistant of wheter I should convert the polar coordinates to cartesian, or plot based on the angle and the curve.

The function can be easily plotted in cartesian coordinates with functions "fplot". Refer the below mentioned link:
