WebMar 20, 2024 · When studying derivatives of functions of one variable, we found that one interpretation of the derivative is an instantaneous rate of change of \(y\) as a function of \(x.\) Leibniz notation for the derivative is \(dy/dx,\) which implies that \(y\) is the dependent variable and \(x\) is the independent variable. WebApr 24, 2024 · To estimate a partial derivative from a table or contour diagram. The partial derivative with respect to \(x\) can be approximated by looking at an average rate of change, or the slope of a secant line, over a very tiny interval in the \(x\)-direction (holding \(y\) constant). The tinier the interval, the closer this is to the true partial ...
