    Do we need to know Newtons' law of cooling for differential equations?
    Nah, you just need to know how DE's work.

    Not by the end of the today, no. Probably by Tuesday or something. I need to get some revision done and I want to make some videos too.

    ab=7500
    a+b=-200

    Solve for a and b

    Yeah, that doesn't make sense - it's of the form P \implies Q with P true, and Q false so that P \implies Q will always be false. What's the actual question?

    A* in C4

    B in S2

    Just finished my 4th C4 paper and scored 72/75 -> 96% ums = A*

    I should have really scored 74/75 stupid mistakes. :stupido:
    So far I've scored: 86, 87, 96, 96 and still plenty of past papers to do.

    We're all gonna make it!

    I would have thought you would use parts.

    Oh yeah that'd probably work, I didn't think to use that because it was in one of the earlier exercises before parts.
