AI Thread Summary
The discussion revolves around a discrepancy in calculations between Maple software and manual computations, where Maple outputs 65.03 while the manual calculation yields 59.99. The key issue identified is the unit of measurement for theta, with one calculation using degrees and the other using radians. This difference in units is crucial as it leads to the significant variation in results. The participants express relief in resolving the confusion regarding the units. Understanding the correct unit of measurement is essential for accurate calculations in mathematical software.

Hi all!

I have tried to calculate a1 using Maple as shown here: http://screencast.com/t/iV1XwJ1CXiqU

The problem is when I do this exact same calculation by hand with the exact same values I always end up with 59.99 but Maple gets 65.03?

How can there be such a big difference?

Thanks!

What are the units of theta, degrees or radians?
 
The following Mathcad 15 implementation makes it look like Maple's 'correct' answer uses radian measure for θdw and you've used degree measure.

No worries. Been there, done that and worn the T-shirt to shreds.
