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?

• Precalculus -

sqrt(x^2+y^2) = 4 [sqrt(x^2+y^2) ]/y

y = 4
(of course :)

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..
