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 :)

    add is counterclockwise

  • Precalculus -

    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..
