Choose a function in the lower part of the Elements pane. These functions are also listed in the context menu of the Commands window. Any functions not contained in the Elements pane need to be typed manually in the Commands window.

個別函式︰
乘冪
插入 x 的 y 次方。 您也可以在 [指令] 視窗中輸入 <?>^{<?>}。可將 ^ 字元替換成 rsup 或 sup。
您也可以利用索引或指數執行函式。請試著在「指令」視窗中輸入下列字串︰sin^2x+cos^2x=1。func f_x def{partial func f}over{partial x} 也是個不錯的函式範例。
在「指令」視窗中手動輸入時,請注意空白字元對於一些函式結構而言是不可省缺的(如,abs 5=5 ;abs -3=3)。
