For Question 6.b) ii) of the 2008 HSC exam, you would find the perpendicular distance from the focus to the line, and as a result you get an absolute value in the numerator. Why would you remove the absolute value?

why is sec theta > 1? I thought diagrams were just like... guidelines. Just because P is in first quadrant shouldn't mean there is a restriction on theta?

I think QZP is saying what if theta is between 90 and 270
Because then sec(theta) becomes negative

Oh, well in that case the diagram shows that P varies on one arm of the hyperbola, meaning that -90 < theta < 90 meaning sec is positive.

Would you please stop that damn frog from moving. I'm wondering what is going on below the viewing window.
