One more for you mathematical wizz kids, another one on trigonometry:

Tan a = _1.5_ can't figure out how to get from this point.
6.598 to this point

Tan a = 0.758

a = Tan-1 0.758

a = 37.16

Tan(\alpha) = \frac {1.5}{6.598} = 0.2273

I'm guessing that the reason you can't get to

Tan(\alpha) = 0.758

is because the fraction is wrong. What I see is 1.5 / 6.598 = 0.2273.

Tan^{-1}(0.758)\, =\, 37.16\, degrees

Tan(\alpha) = \frac {1.5}{6.598} = 0.2273

I'm guessing that the reason you can't get to

Tan(\alpha) = 0.758

is because the fraction is wrong. What I see is 1.5 / 6.598 = 0.2273.

Perito, thanks once again for your help, there seems to be quite a few mistakes in this project, which takes a lot longer to study and more difficult
cheers
