Yes that is OK. It looks like this will simplify to the equation for a straight line that is perpendicular to the line theta = 20 degrees and goes through r = 2, theta = 20 (x = 1.879, y = 0.684)
Expand the cosine function to
cos theta cos 20 + sin theta sin 20
and you have
2 = x cos 20 + y sin 20
which is the equation of a straight line.
I have to graph the following:
2 = rcos(theta-20 degrees). I put it in the form r = 2/cos(theta-20degrees). Is this correct? I am having trouble with my table of values.
I would appreciate your help. Thanks.
