Bug in article 893? (HP 35s Triangle solver)  Dave Britten  05132009 In article 893, there's a rather nice triangle solver, though I think there's an error in the calculation of the 2nd SSA solution (menu option 6). Observe this bit of code:
T096 CF 10 I see two problems with this. First, ACOS(1) is always zero, so W (angle 3) is just negated, whereas it should be replaced with its supplement(ACOS(1)W). The second problem is that it's actually angle 2 (V) that needs to be replaced with its supplement, not angle 3 (W). I've made the following changes. Anybody care to confirm that this makes sense? It looks like I'm getting the correct results now.
