hallowon: Take CS if you love programming. You're going to have one hell of a time! mp3car: They do teach how a bit is stored in a memory and how processors work to a CS major. That's why they have courses like Digital Logic Design -> Computer Architecture -> Computer Organization and Assembly...

You need to practice more to overcome that fear. Try to assign a task for yourself or take up exercise questions from other C++ programming books and try to solve them.

It a really great book! hf :P

I am not sure if its the correct method but I hope it helps. 1st evaluate its limit b/w the interval 0 to Pi/2. Then Calculate it from Pi/2 to Pi. The total area has to be the sum of them which will be equal to infinity :D.

@rock.freak667: I know but I got a little confused by the structure of the equation. @LCKurtz: Thanks that helps me understand the concept better :) @Mark44: I actually though about that after posting :D Thanks for the help guys =)

I don't understand why a circle can't have negative radius. For example, consider this circle with equation x^2+y^2=0, which has its center at origin and passes through points P(x, 0) & Q(-x, 0). If the radius of a circle is defined as the distance from the center to any point on the circle...

Would you please elaborate why?

Nice, here's another definition I found while looking for a better explanation. "A Conic is the set of all the points whose distance from a fixed point bears a constant ratio to its distance from a fixed line. The fixed point is called the focus, the fixed line is called the directrix and the...

Meanwhile this might help. "The directrix of a conic section is the line which, together with the point known as the focus, serves to define a conic section as the locus of points whose distance from the focus is proportional to the horizontal distance from the directrix, with r being the...

For an ellipse the equation of directrix is given by x=± a/e. It's been a while since I've studied them and its late here so I have to go to bed now :). I'll revise my course tomorrow and try to find out the answer to that tomorrow.

The general equation of circle are in the form of x^2+y^2+2gx+2fy+c=0 and since the equations that you mentioned are in this form I am pretty sure they're a circle.

If I am not mistaken, the directrix is not drawn in that figure. This might help.
