May be it is stupid question but it has been long time since I took calculas course.

How I solve sine(theta)d(theta)

i have to multply certain number with: sine(theta)d(theta) as weighting factor in microsoft excel

what is 'C'

I have to solve it in number

Sorry - Sep 12th 2008, 07:17 AMadefris@yahoo.comSine(theta)d(theta) ?
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 - Sep 12th 2008, 08:34 AMhatsoff
It sounds like you may not need to take the integral. Can you please post the problem you're trying to solve in full?
