Maple calculates the wrong answer?

[dscot]

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 θ_dw and you've used degree measure.

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