Unfortunately, Maxima's ability to deduce inequalities is very limited. This isn't a bug, just a limitation. We are happy to have people work on improving this subsystem, although of course it will never handle every possible case.

I am not sure why maxima is not identify that "a" is positive.
The prompt transcribed is:
a:1-t^2/2; assume(t>-1 and t<1); is(t>0); The output from maxima is:
(%i1) a:1-t^2/2; assume(t>-1 and t<1); is(t>0); is(t>-1); 2 t (%o1) 1 - -- 2 (%o2) [t > - 1, t < 1] (%o3) unknown
