sin button doesnt work

[pari]

can someone help me wit my sin button
this what i tried:

VisualBASIC:

Private Sub cmdSin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSin.Click         num1 = Double.Parse(txtC.Text)         txtC.Text = " "         op = "sin"         txtC.Text = (Math.Sin(num1) * Math.PI / 180)

In what way does this not work?

I have two suggestions however I do not know how well either will work, sometimes there's a rounding error when dividing ints and doubles, try dividing by 180.0 instead.

Also I noticed you have brackets around your calculation, I think VB implicitly casts, but just to be sure why not explicitly cast the calculation to string

The last line should instead be:

VisualBASIC:

txtC.Text = Math.Sin(num1 * Math.PI / 180)

The angle must be converted to radians BEFORE using it in the Math.Sin(x) function.
