This tool helps you to determine the uncertainty (or error) of any mathematical expression that contains physical quantities with uncertainties. It follows the rules of the Gaussian error propagation: If f is a function of the independent variables X and Y, written as f(X,Y), then the uncertainty in f is obtained by taking the partial derivatives of f with respect to each variable, multiplication with the uncertainty in that variable, and addition of these individual terms in quadrature. Error calculated by this tool (numerically): 56.882447776373766 Keep in mind that this tool carries out NUMERICAL calculations which do not have the same value as an*lytical methods. However, in all known cases the deviations between numerical and an*lytical results were negligibly small. methods are available and can be used in the formula field: acos(x) Returns the arccosine of x, in radians asin(x) Returns the arcsine of x, in radians atan(x) Returns the Returns the value of Ex log(x) Returns the natural logarithm (base E) of x pow(x,y) Returns the value of x to the power of y sin(x) Returns the sine of x (x is in radians) sqrt(x) Returns the square root of x tan(x) Returns the tangent of an angle Furthermore Euler's constant and Pi are represented by E and PI respectively.
