Error Analysis in angle

    URGENT URGENT ..... Error Analysis in angle

    1. The problem statement, all variables and given/known data

    This is very urgent i could not find out how to find the error in my angles... using calculus
    this is not my level but i must do it somehow..
    i would love to see some steps that i can follow.

    i know that for example E = mgh
    dE/dm = gh
    dE/dg = mh
    dE/dh = mg

    but how do do the same for
    theta = Sin(o/h)

    someone gave me this step but i do not know how to proceed from here...

    please help.... this is very urgent...
    2. Relevant equations

    3. The attempt at a solution

    Relax. I'm going to sleep now, but I've posted a response in your Calculus thread. Check there.

    Re: URGENT URGENT ..... Error Analysis in angle

    Well, this is only true if these derivatives are partial derivatives (normally written as follows):

    ∂E/∂m = gh

    Well, you need to find out the derivative of the sine function, which is relatively simple. Do you know any calculus?

    no our grade 12 class is only past 1st term.
    we have not yet learned calculus... but forsome reason we must know it by tom for our
    assignment.. help
