Серия maclaurin для sin (x)

Question

Я написал программу для вычисления sin (x) с использованием серии Maclaurin, но когда я попытался отладить ее, она выдала ошибку переполнения. Вот код, может ли кто-нибудь помочь мне?

Public Class Form1 
    Private Function sin(ByVal x As Double) As Double 
     Dim sinx, radx, abc As Double 
     sinx = 0 
     radx = x * Math.PI/180 
     For i = 1 To 20 Step 2 
      abc = (Math.Pow(-1, (i/2)) * Math.Pow(radx, i))/factorial(i) 
      sinx += abc 
     Next 
     Return sinx 
    End Function 

    Private Function factorial(ByVal n As Integer) As Integer 
     If (n = 0) Or (n = 1) Then 
      Return 1 
     Else 
      Return n * factorial(n - 1) 
     End If 
    End Function 

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load 

    End Sub 

    Private Sub BtnCalc_Click(sender As Object, e As EventArgs) Handles BtnCalc.Click 
     Dim x As Integer 
     x = Val(TxtInput.Text) 
     TxtAns.Text = sin(x) 
    End Sub 
End Class
