    I sleep at like 12pm~1am and wake from 8am~9am, depending on which days I have free periods early. But average 8 hours or so. Woot. xD

    Problem involving maxima & minima

    Okay I got it. I think. C = (500/v)(150 + v2/80) = 75000v-1 + 25v/4 C' = -75000v-2 + 25/4 St. Points at C' = 0 75000v-2 = 25/4 300000v-2 = 25 1/v2 = 25/300000 v2 = 300000/25 v = 110, -110 v >= 0 Therefore 110km/h

    Problem involving maxima & minima

    Holy crap. I forgot all about Maximum and minimum. I have no idea how to do this anymore. Damnit. Whew, glad I found this thread. =D Do you have the answer to the question? Is it 77km/h? I have a weird feeling I'm way off.. Nevermind. I'm horribly wrong.

    I Need a UAI of 70%

    A UAI of 70 shouldnt be hard to achieve. I dont think the subject you're doing scale particularly well but as long as you get good marks in your assessments relative to those in your grade doing the same subject, then you'll easily make 70.

    Trigonometric Values

    0∫4√3 dt / (16 + t2)3/2 ----------------------- Let.. t = 4 tan Ө dt = 4 sec2Ө dӨ when t = 0, Ө = 0 when t = 4√3, Ө = pi/3 ----------------------- Therefore 0∫4√3 dt / (16 + t2)3/2 = 0∫pi/3 (4 sec2Ө) dӨ / (16 + 16 tan2Ө)3/2 = 0∫pi/3 (4 sec2Ө) dӨ / (4√(1 + tan2Ө))3...

    Hahaha. We need to take all the love advice on this whole BoS forum and make a FAQ for boy/girlfriend problems. "Harden Up" would be the answer to half of them. xD

    I think thats right. Assuming i didnt miss something while typing it up. In the end I got 25pi/4 Whats the answer meant to be?

    Trigonometric Values

    0∫5 (25 - x2)1/2 dx ----------------------- Let.. x = 5 sin u dx = 5 cos u du when x = 0, u = 0 when x = 5, u = pi/2 ----------------------- Therefore 0∫5 (25 - x2)1/2 dx = 0∫pi/2 (25 - 25 sin2u)1/2 (5 cos u) du = 0∫pi/2 root(25 - 25 sin2u) (5 cos u) du =...

    Bird and stone = hard?

    Yes but. Say h was lower. Therefore max height is lowered making the parabola flatter. Which means that the horizontal component will have to increase to reach the bird? Okay I'mma head to sleep. This makes no sense at all right now.

    Bird and stone = hard?

    I still dont see it. Or maybe I've got something on my mind and Its wrong. Height of the pole is variable, right? Wouldnt the horizontal component of the rock vary as it was lower or higher? Maybe its cause I'm sleepy. I dunno. But it just doesnt make sense at the moment.
