WebMultivariable calculus is used in many fields of natural and social science and engineering to model and study high-dimensional systems that exhibit deterministic behavior. In economics, for example, consumer choice … Webthat is the derivative of the function at $a$ with respect to $x_i$ and other variables held constant, where ${\bf e^i} = (0, \dots, 0, 1, 0, \dots, 0)$ ($1$ is $i$-th from the left). These …
WebIf you use nested diff calls and do not specify the differentiation variable, diff determines the differentiation variable for each call. For example, differentiate the expression x*y by calling the diff function twice. Df = diff (diff (x*y)) Df = 1. In the first call, diff differentiates x*y with respect to x, and returns y.
