x‡ (Root) x‡ (xth root) returns the xth root of value. You can use x‡ with real or complex numbers, expressions, and lists. xthrootx‡value fMin(, fMax( fMin( (function minimum) and fMax( (function maximum) return the value at which the local minimum or local maximum value of expression with respect to variable occurs, between lower and upper values for variable. fMin( and fMax( are not valid in expression. The accuracy is controlled by tolerance (if not specified, the default is 1âL5). fMin(expression,variable,lower,upper[,tolerance]) fMax(expression,variable,lower,upper[,tolerance]) Note: In this guidebook, optional arguments and the commas that accompany them are enclosed in brackets ([ ]). MathPrint™ Classic nDeriv( nDeriv( (numerical derivative) returns an approximate derivative of expression with respect to variable, given the value at which to calculate the derivative and H (if not specified, the default is 1âL3). nDeriv( is valid only for real numbers.
