iLogic basic math equation returns wrong value?

[william]

Hello Everybody

I type the below equation into ilogic:

Carcase_OAL_A = Tan(Corner_Angle_A/2) * Booth_Depth

Corner_Angle_A = 60deg 

Booth_Depth = 635mm

I should get a value of 366.617 for Carcase_OAL_A

Instead I get -4067.38mm

I type it in like this:

Carcase_OAL_A = Tan(Corner_Angle_A / 2 ul ) * Booth_Depth

I get -4067.38mm again

I type it in like this:

Carcase_OAL_A = Tan(30) * Booth_Depth

I get -4067.38mm again

I type in this equation:

Carcase_OAL_A = Tan(Corner_Angle_A) * Booth_Depth

I get a value of 203.22mm

It does not let me divide the angle parameter within the tan brackets. When i hover the mouse over the tan function the example shows a equation within the tan brackets. Can anyone explain what is going on?

Hi @william 

The Tan-function takes arguments in radian, not degree. Since your parameter is in degree you'll have to convert it its corresponding radian value. Like so:

Carcase_OAL_A = Tan(Corner_Angle_A/2 * PI/180) * Booth_Depth
