    If you look at pi - the angle, it is in the second quadrant, where tan is negative. By this logic, tan is negative in the 4th quadrant 2, as the association accute angle is the same. Atleast, thats how I saw it :P

    Okay, so f(x) = 1 + (2/x+1) The +1 is a vertical translation, and you already know the shape of the curve 1/x, in that regard, (x+1) is a horizontal translation of -1. And the factor 2, is a stretch. As for the range, 2/(x+1) will never be zero, so think about where the curve tends to as x...

    PHYSICS PAPER 2 HELP and NOTES

    Uhh. I can tell you the way I did it, but it is a bit backwards. As we know the reading on V1 is 4V, and the resistance is 10 Mega Ohms, or 1 x 10^7 Ohms. Using V=IR you can find the current, which is 4 x 10^-7 A. Then, using V=IR again, the second voltage being 2V, the resistance of the...
