    Is it risky to do Extention 2 Maths

    if you want to do it, then do it with your attitude at the moment you'll probably do well in it To get a tutor or not is up to you. Some people learn better with a tutor, some can learn from their teachers...etc

    Any 4u maths students cbf with 2u?

    its probably for the best as it allows people to drop 4unit later on and get an accurate ranking for 2unit later on

    i think he means integrate with respect to r and then rearrange if you have the initial conditions to find c, find c if not, then just move c over as its just a constant
  10. T


    you can, you just have to rearrange the equation you have for t

    You can do this x=\int \frac{1}{2y}dy you cannot do this because its integrating in respect to y and yet you have x x=\int \frac{1}{2x}dy
  12. T


    the first part is correct the second part is not the answer you can only integrate if its 1/2y, not 1/2x
  13. T


    not sure what you mean, but in the first example this is what you're doing x=\int \frac{1}{2x}dy you cant integrate 1/2x if its dy the second example is pretty much correct
  14. T


    i don't think you can do that. You're integrating 1/2x in respect to y not x
