WOLFRAM LANGUAGE TUTORIAL
|D[f,x,y]||multivariate partial derivative|
This is one of the standard palettes for entering mathematical operations. When you click a button in the palette, the form shown in the button is inserted into your notebook, with the black square replaced by whatever you had selected in the notebook.
|EscddEsc||special differential for use in integrals|
|Ctrl+_ or Ctrl+-||move to the subscript position or lower limit of an integral|
|Ctrl+^ or Ctrl+6||move to the superscript position or upper limit of an integral|
|Ctrl++ or Ctrl+=||move to the underscript position or lower limit of a sum or product|
|Ctrl+& or Ctrl+7||move to the overscript position or upper limit of a sum or product|
|Ctrl+% or Ctrl+5||switch between upper and lower positions|
|Ctrl+Space||return from upper or lower positions|
You can enter an integral like this. Be sure to use the special differential entered as EscddEsc, not just an ordinary .
When entering a sum, product or integral that has limits, you can create the first limit using the standard control sequences for subscripts, superscripts, underscripts, or overscripts. However, you must use Ctrl+% to create the second limit.
