    steps for sketching PRETTY MUCH ANY FUNCTION

    This is an old school method of plotting: http://www.s-cool.co.uk/alevel/maths/fu ... raphs.html For sketching, you need to memorize the most important used functions and then sketch based on those sketches. I'll try to find the sheet which has all the sketches of functions.

    is d/dx the same thing as dy/dx

    y = something. Differentiating y with respect to x is shown by: .d. (y) dx which is equal to dy/dx. I explained it in detail because dy/dx is equal to d/dx only when equations subject is y!

    Physics Here....

    Yes. Terminal velocity is the term for the state an object reaches when the force of drag acting on it is equal to the force of gravity acting on it. When an object reaches its terminal velocity, it no longer accelerates, remaining at whatever velocity it was already traveling or else slowing down.

    Mathematics Grading Query

    To be honest 59/75 in P1 isn't whats called good. With other getting over 70, chances of A* are almost gone and A lies in danger zone. Don't lose hope and try to hit 48+ in P6. That might increase possibility of an A.
