The answer for the first one is $a$ as it should be. However, for the second one I get $|\sin(\theta)|$. Considering that I have already assumed $0<\theta<\pi$, I should not have got the absolute sign. Is this a bug? And is there a way to get around it? |

The Maxima assumption framework is fairly weak: Quoted here: "Maxima's deduction mechanism is not very strong; there are many obvious consequences which cannot be determined by is. This is a known weakness." Of course, so in case that helps. |
