Hi, I am a beginner at Visual Basic 6! I am trying to make a simple program that will allow you to enter an angle, and receive the sine, cosine, and tangent values. the code: Code (Text): Public Class Form1 ' Imports System.Math Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim A As Double = TextBox1.Text Dim B As Double = TextBox2.Text MsgBox((A ^ 2 + B ^ 2) ^ (1 / 2)) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim A As Double = TextBox3.Text Dim C As Double = TextBox4.Text MsgBox((C ^ 2 - A ^ 2) ^ (1 / 2)) End Sub Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim A As Decimal = TextBox5.Text MsgBox("cos" & " " & Math.Cos(A)) MsgBox("sin" & " " & Math.Sin(A)) MsgBox("tan" & " " & Math.Tan(A)) End Sub End Class As you can see this is very rudimentary stuff. The first part of the code is for the Pythagorean Theorem knowing A and B, or AorB and C. The second part will give me the sine, cosine and tangent of an angle in a message box in decimal form. The questions I have: Is there a command that will make the answers appear in fraction form? I am assuming this will replace the "As Decimal" but I can't find anything in the book I have or on the microsoft website. Are there inverse sine, cosine and tangent commands? So I can turn the fraction back into the angle (in radians or degrees) Please forgive me if it is very simple! I am still learning!
