NOTES: [list] [*]My syntax is correct. (Test it: Execute[Tx]) [*]The inequality is also insconsistent with the definition shown in Algebra view. On load, redefinition, Update[], all the inequalities are the same (the last values in the list). However, try dragging the blue line, and changing the value of a. I get all of the following: 1. Correct result 2. Leftmost inequality in the viewport vanishes. 3. Partial list, one column break, clump at the right end. 4. Clumpy shading: dark patches run around as if there are multiple copies of the same object. [*]4. above is a general bug in all inequalities and shaded figures. [*]Zip [ k1 ≤ x ≤ k2, k1, list1, k2, list2] gives the same behavior. [/list]
