The same issue arises when we use CalloutMarker -> Arrowheads[Medium] or CalloutMarker -> Arrowheads[.02] in combination with Manipulate andImageSize -> Full. A simple fix is to use ImageSize -> Scaled[1] instead of ImageSize -> Full: Manipulate[Plot[Callout[x, "x", CalloutMarker -> "Arrow"], {x, 0, 1}, ImageSize ->...

Actually, Mathematica was kind enough to tell me. If you do this: In[] = ToBoxes[λ'] Out[] = SuperscriptBox["\[Lambda]", "\[Prime]", MultilineFunction -> None] You can then make your boxes out of these characters: MakeBoxes[lambdaPrime, StandardForm] := SuperscriptBox["\[Lambda]", "\[Prime]"]; MakeExpression[...

With Tooltips Clear["Global`*"] func = {Sin, Cos, Tan}; quad = Range[Pi/4, 2 Pi, Pi/2]; signs = Outer[ Tooltip[ Sign[#1[#2]] /. {1 -> "+", -1 -> "-"}, Show[ Plot[#1[theta], {theta, 0, 2 Pi}, PlotStyle -> AbsoluteThickness[0.5]], Plot[#1[theta], {theta, #2 - Pi/4, #2 + Pi/4}, ...

The items in the original table look a lot like buttons. Lets try that approach: {{"", "Quadrant", SpanFromLeft}, {"Ratio", "I", "II", "III", "IV"}, {Sin[\[Theta]], "+", "+", "-", "-"}, {Cos[\[Theta]], "+", "+", "-", &...
