I recently was working in class, and we started doing non-right triangles and how to solve them and all. I got bored in class, and decided to start working on a solver of the angles of a triangle given the three sides. After a while, I came up with a program. Yesterday, I got the idea of how to shorten it down.
Now the teaser for all of you: Given inputs of a, b, and c, output A, B, and C in their respective orders. The input has to be in the program.
I got it down to 104 bytes:
Quote: :Prompt A,B,C
:For(θ,1,3
:Disp cos‾¹(((A(θ≠1))²+(B(θ≠2))²+(C(θ≠3))²-expr(sub("ABC",θ,1))²)/(2expr(sub("BAA",θ,1)+sub("CCB",θ,1
:End
Anyone? |

We're repeating ourselves: http://www.unitedti.org/index.php?showtopi...indpost&p=94058
Anyways, for the teaser at hand:
Quote: Prompt A,B,C
{A,B,C
cos-1((.5sum(Ans2)Ans-Ans3)/prod(Ans
(39 bytes)
