My mistakes were thinking that PI was only in radians, and 3.14 radians is equal to half the circumference. But I now know that PI is a little bigger (3.14 bigger) than three diameters of the circle, and radian is the length of radius. Thank you!

Thank you, yes units are important, but what about the answer? C=2∏, 360* ( ∏ radians/180* ) = 2∏ radians = circumference in radians = 360* (.0174) = 6.28, so two PI equals circumference. C=2∏ ,but what was said was C=2∏r. sorry for my confusion.

Am I correct, ∏ is 3.14 radians. If so, 360 degrees is a circle, which is the circumference. 360 degrees converted to radians is 360 x ∏/180 = 2∏, Where am I thinking wrong?

You have me thinking now, and I hope it’s OK to ask a question here. I am not sure, but is this true 2 ∏ = circumference?

If: HYP = 26.1725, ADJ = 26, and OPP = 3, a = 90* so, COS (b) = C/A = .9934, or SIN (b) = B/A = .1146, or TAN (b) = B/C = .1154 … How is the inverse function executed on my calculator? Answer: INV- button So, COS ratio – INV button – COS button = angle = 6.58*pitch Thank you very much...

Thank you very much for the helping hand. Trigonometry is awesome. I understand now how to get the ratio. And I found how to use C, S, or T to change angle to a ratio (put in the angle and hit the C, S, or T key on the XP-W scientific calculator, to get the ratio of the sides.), but it was...

That's over my head. Can you please break it down?

I am stuck on the job; I need to find the angles. It’s not an angle or side based triangle, just a right triangle. The lengths are known, A-B-C. What I need to know is the angles, a-b-c. So, a=90*, what formula could I use to find b, and c? Sorry, please make it easy enough for me to work it...
