Private Sub Command1_Click()
Text4 = a / b
Text5 = Sin(Val(Text1.Text) * pi / 180)
End Sub

Private Sub Command2_Click()
End
End Sub

Private Sub Form_Load()
Text1.Text = ""
Text2.Text = ""
Text3.Text = ""
Dim a As Double
Dim b As Double
a = Sqr(Val(Text1.Text))
b = Val(Text2.Text) + Val(Text3.Text)
End Sub
