Symbolic Manipulation 259
In some cases, you may be able to create an equivalent single-statement function. For
example, consider a piecewise function with two pieces.
• If you were to create a multi-statement user-defined function with the form:
Note: To select nInt from the Calc toolbar menu, press … B:nInt.
When: Use expression:
x < 0
x
| 0
Lx
5 cos(x)
Func
If x<0 Then
Return ëx
Else
Return 5cos(x)
EndIf
EndFunc
Then numerically integrate
y1(x) with
respect to x.
Define
y1(x)=Func:If x<0
Then: ... :EndFunc
