Figure 7From: Calculation of vectorial derivatives for functions of a quaternion variable and their propertiesSide views showing the size of the remainder term of \(D\cos (p)\) that is output according to the size of a positive real y in a certain range of x using Maple 20 performance. (a) Graph observed perpendicular to the yz plane with \(x = -10\cdots 10\), \(y = 0\cdots 20\). For x within \(-10\leq x\leq 10\), the remainder term becomes 0 in a region where the size of y is less than about 15. (b) Graph observed perpendicular to the yz plane with \(x = -20\cdots 20\), \(y = 0\cdots 60\). For x where \(-20\leq x\leq 20\), the remainder term is zero, excluding the area where y is larger than 55Back to article page
