math wrong?

[JamesB]

I am trying to use the math.sin(value) function but it seems to give me the
wrong answer!
For instance, math.sin(1) is returning 0.84147098.... whereas windows calc
doing 1 then pressing sin gives me 0.017452406.....

Where am I going wrong? Or can't VB add up?

system.math.sin works in radians, the answer you got forom calculator is
sin(1) in degrees

'Math.Sin' is a .NET Framework function. Like in VB6, mathematical
functions deal with radians. You'll may want to convert them to degrees
using the formula presented at
