    Partial Fraction Decomposition

    Now, I have NO idea how to do this, but try this: On this equation, \frac {1} {4} = -B - Ci what values of i would eliminate C, apart from 0? After that, you solve for B and then you can insert that in 1 = \frac {1} {4}\cdot(s^2 +4) + (Bs +C)\cdot s

    Solve tan2x(1-tan^(2)x=2/(2/root 3): 0-360

    I believe this is incorrect... shouldn't it be the square root of 3, and not of 2?

    How long will a ball of paper take to fall from a height of 45 meters?

    Well, alright then... Thanks for all your help, LowlyPion, but I guess I'm going to have to leave this one for later. Thanks again :)

    How long will a ball of paper take to fall from a height of 45 meters?

    Thanks :) Alright, so I'll attempt again (losing the inches, as you said) and I'd try experimenting to see what the drag coefficient was, but I lost the paper when I dropped it. So anyway, if I fix these two, should the whole equation work? And, isn't there a simpler way to find the same...

    How long will a ball of paper take to fall from a height of 45 meters?

    Alright, so, first of all, I created this problem myself. I made this to study, so I considered it as my homework. 1. How long will a crumpled ball of paper that is 3 inches in diameter take to fall 45 meters IN FREEFALL, knowing that the sheet of paper used to create the ball was 210mm x 297mm...
