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

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:

Code: Select all

LBL"f"
MVAR "x"
RCL "x"
sin
RTN
END 
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
mcc

You asked the same question before, and I answered it before: viewtopic.php?f=15&t=2121&p=10007#p10007

You never acknowledged that reply; I guess because you never read it?
