### Math question: Integration of sin(x) 0...180 deg

Posted:

**Fri Jun 14, 2019 10:44 am**Hi,

The integration of sin(x) from 0...180 degree is: [ -cos(x) ] 0...180 = (-cos( 180 )) - (- cos( 0 )) = 2

As program for the Integrator of the DM42:

Gives me for LLIM=0, ULIM=180, ACC=0.0001

114.591...

Any of my attempts to spot any conjunction between 180, 114.591 and 2 failed.

Mode is set to DEG and RECT.

I am sure I failed here...

...but where?

Cheers
