So theta =0 ?

So theta =0 ?
Yes. Now think about what values of corresponds to and , hint: the y-axis is at to the -axis.

Sorry, i dont understand how to do that.
6. The Cartesian equation can be found here but it is unnecessary.
Solve for when x and y =0 and did the corresponding θ values.

What does an x-axis or y-axis intercept mean for the x,y coordinates?

Y=0 at an X intercept, and X=0 at a Y intercept.
so B is (?,0) and A is (0,?).

Yes.
10. (Original post by Zacken)
Yes.
I just dont see how i can plug this in to get x value for B and a y value for A.

Find a value of that makes zero then plug this into your . Then vice-versa.
