Command1_Click preparation process, input x, n, according to the following formula for calculating the value of polynomial y, requires the use of the Select Case statement,
X2 + 1 n=1, 2, 3
Y=X1/3-5 n=5
8 + x2 X3-1 & lt;=n

CodePudding user response:

N in different values, x and y in a different way of calculation, piecewise function.
This as long as you take a look at the select syntax description and course can understand.

 Sub test () 
Dim n As Integer 
Dim As Double y 
Dim x As Double 
'the input values 
N=5 
The Select Case n 
Case 1, 2, 3 
Y=x ^ 2 + 1 
The Debug. Print y 
Case 5 
Y=x ^ (1/3) - 5 
The Case Is & gt;=8 
Y=x ^ 3 + x ^ 2-1 
End the Select 
MsgBox 'output the answer y 
End Su
