    Maths Question

    Hey guys, i really need help with this question. I know neil is pretty good at this. This is related to error analysis, cant understand a word:

    Determine which quantity or combination of quantities you would plot on the x and y axis in order to plot a straight line and thus determine the constant c in the following question. (f, r are variable and c, b are constants). we need to identify x, y and c.

    a) f^2 = c / (r^3)
    b) f = L ^ -rc
    c) f = rL ^ -c
    d) f = cr - b
    e) f = c/r - b

    I know its a hard question, but is there anyone who could help me with it?

    If you want a straight line, you always want the equation to be broken down to a Y= mx+c form, where C is the y-intercept and m is the slope.

    So if you have f ^ 2 = c/(r^3), you can essentially think of it as f^2 = c(1/(r^3)) + 0
    Now it is in the y=mx+C form, where y = F^2, m = c, x = 1/(r^3) and C =0

    You can treat F^2 or F^3 or F^n as y, it wouldnt matter- as long as there isnt another variable in the left hand side.

    Yup!
    Though mind you- some profs are annoying about this- they dont like powers in the left hand side so he might be a bit cheesed off that you left it as F^2 instead of taking the square root on both sides and then fitting it into the y=mx+c format.

    Put it in general form, you girl.
