Example 5 Interpret a Partial Derivative Suppose 2 (, ) 2 4 x fxy x y y . Earlier in this section, we found that 22 22 2,4 2,1 48 yy1 x fxy f y Interpret the value of the partial derivative along the slice x 2 illustrated below. Solution Since the value of the partial derivative with respect to y is negative, z must be decreasing as y increases along the slice. To see this graphically, we need how to get to byron bay from surfers paradise The partial derivative of the "Zeta mapping" with respect to its second argument has an ambiguous meaning: the argument to D could be the Zeta mapping of two or of three variables. The derivative is thus returned uncomputed:

- MATH 162: Calculus II Framework for Tues., Mar. 6 Diﬀerentiability Today’s Goal: To understand the relationship between partial derivatives and continuity. The Mixed Partial Derivatives We have learned that the partial derivative f x at (x 0,y 0) may be interpreted geometrically as providing the slope at the point (x 0,y 0,f(x 0,y 0)) along the curve that results from slicing the surface z
- here the coeﬃcients A, B, C are given as in (1) by the second partial derivatives with respect to u and v at (0, 0), or what is the same (according to the chain rule—see the footnote below), by the second partial derivatives with respect to x and y at (x 0 ,y 0 ).
