Help with vb equation for trig values

This is making my brain hurt

cot A = b * pi / c

j = Pc * cos A * 0.3183

I have Pc, b and c and in these calculations A is degrees. As vb uses radians how does this need to be written to get value j?

Can someone help with this then?

Cot A = 1/Tan A = B

I have B, what do I do to it to get A? (in radians)

I need A in radians to then put it into the second equation above to get J

A= 0.090757121103705 Radians

Cot A = 1/System.Math.Tan(0.090757121103705) = 10.9881501380931

Here’s a couple of functions that may be helpful.

Private Function PI() As Double
‘Returns 3.14159265358979
‘If using a calculator, set the mode to Radians.
PI = Atn(1) * 4
End Function

Private Function DegreesToRadians(dblDegrees As Double) As Double

DegreesToRadians = dblDegrees * (PI / 180)

End Function

Private Function RadiansToDegrees(dblRadians As Double) As Double

RadiansToDegrees = dblRadians * (180 / PI)

End Function
