Question
The polar equation of a graph is given below:
r=4/sin(theta)
Give the equation of the line in rectangular coordinates.
If you rotate this graph 40 degrees counterclockwise about the pole, would you add or subtract 40 degrees to θ?
Subtract?

sqrt(x^2+y^2) = 4 [sqrt(x^2+y^2) ]/y
y = 4
(of course :)
add is counterclockwise
y = 4
(of course :)
add is counterclockwise

So the answer for "Give the equation of the line in rectangular coordinates." is sqrt(x^2+y^2) = 4 [sqrt(x^2+y^2) ]/y?
Or is it the y=4?
Again, that's probably a silly question..
