In the post How to Extract data points from plot in mathematica to redraw it with another program?, I found out Tan @ x and Tan[x] are generating different data on export. What the context under which @ is used in Mathematica. For example, Catenate @, Tan @ x and Sort @ Select.

  • $\begingroup$ Tan[x] is the same as Tan@x, as well as x//Tan $\endgroup$

  • $\begingroup$ Tan[x] is the same as Tan@x, so presumably your have an order of operations problem. Try parentheses, or post simple code that illustrates the problem. $\endgroup$

  • $\begingroup$ When a piece of code doesn't do what you expect it to, always show an example in your question. See sscce.org for guidance on how to write a useful example. $\endgroup$
