Look this is what I want to solve in excel
Y = integral[Xsin(theta)d(theta)]
The integral is broken into 5 (i=1 to 5)
X is the measurments. So I want to solve sin(theta)d(theta) as a weighting factor for the measurment X.
So theta is the midle angle for each circular rings of :
Ring 1: 0.0 - 13°
Ring 2: 16.7 - 27°
Ring 3: 32.4 - 43.4°
Ring 4: 47.3 - 58.1°
Ring 5: 62.3 - 90°
Hope some one is out there to help
