    How to do this question.

    RTP: x^2+y^2+z^2+2xyz=1 given that: arccos(x) + arccos(y) + arccos(z) =pi I have gotten expressions for xyz from taking the cosine and sine of the given statement (bottom one), i keep getting a bunch of sqrt(1-x^2) and such for each variable and I cant seem to rearrange to get the top expression.

    ?? Is it hard to get atar over 85 ??

    Since most of your subjects i pretty rote subjects. For chem and phys, its gonna be next to impossible to learn everything well conceptually, so your best bet would be to get good at the easy things, ie memorise typical calculations (e.g. calculating ph, back titrations, Keq calcs), be...

    Physics MOD 7 Confusion - any help asap is appreciated

    yeah, like you said, a key thing was that it was in theory that maxwell calculated v=1/sqrt(epsilon x mu), so obviously practical test had to confirm this. and iirc, maxwell did not yet know that there was a continuous spectrum of wavelengths of light, so scientists had to measure all...

    How the hell do i do this

    capacity is just 380-220=160 ml (as water denisty is 1ml/g from data sheet). Thus the density of kerosense is (351-220)/160 =0.82 g/ml.

    HELP!!!!!! induction question

    im assuming you got up to proving for K+1 and you got up to: kH(k)+1+H(k) after you plug in the assumption to LHS of the statement for n=k+1 then factor as such: H(k)[k+1]+1 then factor out (k+1) [k+1](H(k)+1/(k+1)) then note H(k) + 1/(k+1) = H(k+1) thus you get [k+1]H(k+1) as required...
