I have a basic question on how to take derivatives using Math Palettes:

I would like to get the derivative of cos(k*x - w*t) with respect to x

Typing D[Cos[k*x - w*t], x] successfully returns k Sin[t w - k x], but I also want to learn to do it using Math Palette. When I use the tool like I did below, I cannot do it. How do I fix this? What am I doing wrong?

Math palette

  • $\begingroup$ How did you get those differential ds? Did you copy them from the integral expression? Which palette are you using? $\endgroup$ – MarcoB Dec 11 '19 at 16:15
  • $\begingroup$ The fancy notation for derivatives is like this in Mathematica: \!\(\*SubscriptBox[\(\[PartialD]\), \(x\)]\(x^2\)\) (copy this to a notebook to see it formatted) $\endgroup$ – Szabolcs Dec 11 '19 at 16:16
  • $\begingroup$ @MarcoB, I got the d's from Palettes > Basic Math Assistant > Typesetting. $\endgroup$ – rr_ed Dec 11 '19 at 19:59

The palette's typesetting shortcut Derivative notation which looks like this:


is intended for inline math typesetting in a text cell. You use it typeset math expressions in text cells. Like this:


To take a derivative in a calculation, i.e., in an input cell, use the Single variable derivative shortcut.
