Can you forward my email to the people in charge of Maxima?
Thanks in advance.

Good evening.
I am using Maxima both on Windows and on Android(Nexus 7).
I run the same problems, symbolic ones, on both computers and I have
some differences, in the format of the output.
Some parenthesis can be missing on the Android Maxima versus the Windows
version for symbolic expressions, i.e. some more general problem of
meaning of an answer. For example cos Hzx, is it cos(hz) times x or
cos(Hzx)? Big problem for more complicated expression.
I run the following example :
load(scifac);
eq: 'diff(u,z,2)-Ha^2*u-Re*Px+K*Ha^2 = 0;
sol : ode2(eq,u,z);
solution : bc2(sol,z=-1.0,u=0.0,z=1.0,u=0.0);
combine(solution);
gcfac(%);
subst(%i*z,z,%);
demoivre(%);
subst(z/%i,z,%);
expand(%);
subst(%i*HA,Ha,%);
demoivre(%);
subst(Ha/%i,Ha,%);
final: factor(%);
You have the hardcopies of the Windows and Nexus 7 where you can see the
missing paranthesis in the last expression cosh Ha instead of the
expected cosh(Ha) !!!
Is it a known problem in Maxima? Something specific to the Android version?
Thanks in advance for your answer.
Best regards.
Jerome Huck.
