Since g(x, y) = 0 defines y as a differentiable function of x, calculation of that derivative proceeds just as above: d dx [f(x, y(x))] =f(x, y) ( x x , y x ) = f(x, y) (1, y'(x)). It also contains the assigment at the very end. stream The Mathematica differentiation command has the form D[F[x,y,],z], where the last variable specifies the one with respect to which to carry out the differentiation. is interpreted as {{1,2},{3,4}}: When an input evaluates to TableForm[expr], TableForm does not appear in the output: Out is assigned the value {{1,2},{3,4}}, not TableForm[{{1,2},{3,4}}]: Even when an output omits TableForm from the top level, it is not stripped from subexpressions: The output does not have TableForm in it: However, the variable e does have TableForm in it, which may affect subsequent evaluations: The determinant is not evaluated due to the intervening TableForm: Assign variables first and then apply TableForm to the result to maintain computability: MatrixForm Grid TextGrid GraphicsGrid TableView ArrayPlot PaddedForm.

The key point is that for any value k, the function f assumes the value k precisely on the level curve f(x, y) = k. To find the maximum or minimum value of f on the curve g(x, y) = 0, it is thus enough to plot the level curves of f and find the largest and smallest values of k for which the curve g(x, y) = 0 intersects some level curve f(x, y) = k. The following figure illustrates the idea for the problem from Example 10.4 of Section 4.10: find the maximum value of f over the curve 2 x 4 + 3 y 4 = 32, if the formula for f is f(x, y) = ( x 2 + y 2 ) 1 / 2 .
