Thus, if f is nonzero, then it is parallel to g, that is. % So Marco's first line of code exactly answers your question? /Type /XObject Add a comment 2 Answers Sorted by: 1 Here is a code I wrote in Mathematica to perform Newton's Method. TableForm should be used for viewing data in an easy to read format, but shouldn't be used as a wrapper when storing data. Knowledge-based broadly deployed natural language. In your second graph you see that the data coordinates are 1 to 5 for x and 1 to 5 for y. The assumption that g y != 0 assures that g(x, y) is nonzero there. Technology-enabling science of the computational universe. Use MathJax to format equations. /a0 << /CA 1 /ca 1 >> Here is data on objects and their dimensions: Use the Alignment option to specify how items in columns should align: Add a row of column headings to the grid.

So, for instance, will apply Sin[Cos[#]]& to each element of the second column, while, will multiply each element on the second column by s, One versatile approach is to use ReplacePart. /Contents 3 0 R Content in a mathematica file is organized as cells. TableForm. "//TableForm") that I'd like to export as an image if possible. Finding distribution parameters of a gaussian mixture distribution Reading in scientific notation from C++ to Mathematica How to draw Fractal images of iteration functions on the Riemann sphere? 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 . /Resources 2 0 R I recognize this was 8 whole years ago, but did you ever get a sufficient answer?

Revolutionary knowledge-based programming language. I was missing the nested map ( /@ ) inside the MapAt in my own attempts. Semicolons at the end of lines suppress printing results of computations. Why does Acts not mention the deaths of Peter and Paul? 2. So it's a simple matter to modify only that column: will apply f to each element of the nth column of mat. Learn how, Wolfram Natural Language Understanding System, Fast Introduction for Programmers: Associations. Note: To remove quotes in title you can use: Update: Post-processing the output of Jen's method to center the label and remove the divider line: Here is another approach using only the functionality of TableForm itself: This nests the list deep enough inside {{ }} so that the column labels provided by TableHeadings are applied only to a single column containing the actual table.

Does the 500-table limit still apply to the latest version of Cassandra? endobj Content in a mathematica file is organized as cells. The stream 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)). Bill White Bill White. To complete the solution to the example, just compute the value of f at the candidates Mathematica found.
