    Uncertainty in Multiplication: Significant Figures vs. Rate

    I'm sorry but I don't think that I understand it, could you give me an example? And I guess my problem is why is this equation \Delta_x f = f(x+\Delta x, y) - f(x,y) correct? I mean why is \Delta_x f equal to that which is in the equation?. Asuming that what quantity is constant? The quantity...

    Uncertainty in Multiplication: Significant Figures vs. Rate

    Thank you. Then at least I was not wrong?

    Uncertainty in Multiplication: Significant Figures vs. Rate

    My point is that it seems stupid to use significant figures instead of the rate of uncertainty in multiplication as the real answer could be far from the answer you would get with significant figures. You won't know how far away your answer could be and sometimes that's neccesary knowledge... am...

    Uncertainty in Multiplication: Significant Figures vs. Rate

    Why do we use significant figures in calculations instead of the rate of Uncertainty? (2,5\pm0,4000)*4,000=(10\pm1,6). The number 2,5 has 2 significant figures, which is the same as we will write in the answer, while it should be only one significant figure in the answer if we take the rate of...

    In Dimensional analysis why is Lenght/Lenght=1 (a dimensionless number)?

    Thanks for all your answers it's my first time posting here so I didn't expect this much ^^ But I believe I have already solved it on my own. If you for example have a graph where both x and y have the same dimension (let's say its lenghth) and you find in the graph that y/x=a, which is in...

    In Dimensional analysis why is Lenght/Lenght=1 (a dimensionless number)?

    In Dimensional analysis if L=Lenght why is L/L=1 (a dimensionless number), and not just nothing more than L/L ? It started with that I was thinking of why degrees do not have any dimension, and then I thought of the definition of radians: q = "angle" s = "a length on the circles...
