1. ## 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?

2. My word they're learning this stuff young these days.

3. Steds please tell me u know how to do it?

4. 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.

5. Thanks C_C, ok so i can now plot this onto my graphics calculator and find out the values on x and y-axis?

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.

7. hmm alright thanks C_C. I might ask for more if i dont get anything

Put it in general form, you girl.

Suddenly i have had a change of heart about doing maths when i get older.
