Homework Statement
Hi, I have the coordinates of an "expression" for a point in a cartesian coordinate system. I'm trying to write it in a polar coordiante system (in function of r and theta) but I don't know how to find the answer
a = y-component of the point
b = x-component of the point
theta = angle between the y-axis and a line connecting the point with the origin
r = distance from the origin till the point
Homework Equations
the expression which I would like to write in a polar coordinate system is:
a.sin(theta) + b.cos(theta)
The result should be:
r.sin(theta).cos(theta)
How to get to this result?
