Students who are taking calculus will notice that these rules are entirely unnecessary. In other classes, like chemistry, there are particular ways to calculate uncertainties. You can simplify much of what you're attempting by the identity: $$\sin\left[\tan^{-1}\left(\frac{y}{a}\right)\right] = \frac{y}{\sqrt{y^2 + a^2}}.$$ The rest is a question of how terms are arranged (divide both sides of what If the uncertainties are correlated then covariance must be taken into account. this contact form

Significant Error Definition For example, if some number A has a positive uncertainty and some other number B has a negative uncertainty, then simply adding the uncertainties of A and B together could give The fractional error in x is: fx = (ΔR)x)/x where (ΔR)x is the absolute ereror in x.

Why do most of us wear wristwatches on the left hand? In fact, since uncertainty calculations are based on statistics, there are as many different ways to determine uncertainties as there are statistical methods.

Phys. (1975 - 1988) J. For example, the bias on the error calculated for logx increases as x increases, since the expansion to 1+x is a good approximation only when x is small. If you're measuring the height of a skyscraper, the ratio will be very low. But when quantities are multiplied (or divided), their relative fractional errors add (or subtract).
