Defining automatic substitution strings doesn't work for some functions

Version: 3.0 - Scientific WorkPlace, Scientific Word, & Scientific Notebook


Attempting to define an automatic substitution sequence for the standard hyperbolic function csch results in Math: csc h instead of Math: csch.


The automatic substitution feature prevents the use of function names that contain previously defined function names as subsets. You can't use the names csch and sech for automatic substitution because the trigonometric functions csc and sec already exist.


Define a Math Name for the function you want, and then assign it to an automatic substitution string with a new name that doesn't contain a predefined function name as a subset. Here's how to define and use an automatic substitution sequence for Math: csch.

  1. From the Insert menu, choose Math Name.

  2. In the Name area, enter csch and choose OK.

  3. From the Tools menu, choose Automatic Substitution.

  4. In the Keystrokes box, type csh or some other keystrokes that don't contain the subset csc.

  5. Position the insertion point in the Substitution area.

  6. From the Insert menu, choose Math Name.

  7. Scroll to find and select csch, and then choose OK.

  8. Choose OK.

  9. Make sure the Math/Text button appears as M. If it doesn't, click the button or, from the Insert menu, choose Math.

  10. Enter csh (or the keystrokes you entered in step 4).

    The hyperbolic function Math: csch appears in gray on your screen.
