What is a Mixed Derivative? Themixed derivative(also called amixed partial derivative) is asecond order derivativeof afunctionof two or more variables. “Mixed” refers to whether the second derivative itself has two or more variables. For example: fXYand fYXare mixed, fXXand fYYare not mixed...
A procedure to get the directional derivative of a function of two variables f(x,y) is to obtain a unit vector that shows the direction in which we are going to calculate the directional derivative, then we have to find the gradient to calculate a scalar prod...
Letq(a,b)be a function of two independent variables, then the partial derivative of a function of two variables can be found by applying the usual rules of differentiation with one exception. That means that if we take the derivative with respect tob, then the second variableais treated ...
2 x ? A function is differentiable if it has a derivative everywhere in its domain. It must be continuous and smooth. Functions on closed intervals must have one-sided derivatives defined at the end points. Use the definition of derivative to find the derivative of f(x) = x2. f ' ( ...

Figure 2. The second derivative test can often determine whether a function of two variables has a local minima (a), a local maxima (b), or a saddle point (c).To apply the second derivative test, it is necessary that we first find the critical points of the function. There are ...
