Okay so I am trying to make a program that solves the law of sines for the ti-84 cse and I got 2 working for the law of cosines, but whenever I run the program on my calc (ti-84 cse) I always get the first answer =1 the second=2 and the third=0 I'm sure its a small bug, but I can't figure it out.
Code: Input "Side a=",A
Input "Angle A=",B
Input "Angle B=",C
180-B-C=D
(sin(C))((A)/sin(B))=E
(sin(D))(((A)/sin(B))=F
Disp "Angle C=",D
Disp "Side B=",E
Disp "Side C=",F
Okay, one quick question first, are those equal signs actually store symbols? Otherwise D,E, and F are never modified. I will see how it works really quick as well.

I haven't a clue, I don't really know what I'm doing, I'm just attempting this with my very, very vague knowledge of computer programming. I don't know if it does store it, that could very well be the problem, but I don't know.
With a bit of optimization:
Code: Input "Side a=",A
Input "Angle A=",B
Input "Angle B=",C
180-B-C→D
Asin(C)/sin(B)→E
Asin(D)/sin(B)→F
Disp "Angle C=",D,"Side B=",E,"Side C=",F
"=" is used to compare values; it evaluates as 1 if the expressions to the left and right of it are equal, otherwise it evaluates as 0.
"→" (the STO→ key) sets a variable equal to the expression that precedes it.
See the TI-84 Plus C Silver Edition guidebook, chapter 16 / page 276. It provides an introduction to programming the TI-84 Plus C Silver Edition. For a thorough course on TI-83 series programm, there's KermMartian's book Programming the TI-83 Plus/TI-84 Plus.
