New issue 3952 by omar.ant...@gmail.com: Sympy cannot compute the integral
of sqrt(tan(x))
http://code.google.com/p/sympy/issues/detail?id=3952
Sympy gives up on integrate(sqrt(tan(x)),x) and returns it unevaluated.
Mathematica
Say I have an expression like:
y = sqrt(2) * sqrt(-x + 4)/2
and then we call powsimp(y), we get:
sqrt(-2*x + 8)/2
is there a way to get
sqrt((-x + 4) / 2), i.e. have the denominator of the fraction be checked
too? I tried looking at the docs but there didn't seem to be a
simplification for

Wolfram Mathematica has Plus and Times which are used for every expression
overloading the + and operators.
I see here that SymPy has Mul, Add, MatMul, MatAdd, VectMul, VectAdd,
TensMul, TensAdd, and so on...
Do we really need all these ones? Couldn't Mul and Add be rewritten in such
a way
They _could_ be rewritten, but it is always easier to start from scratch,
mainly because of all the assumptions that were silently admitted when
writing any of these.
Add and Mul were sufficient for the vectors, forms and multiforms in
`diffgeom`, but there are still corner cases causing bizarre
Can you post a link? The latest commit is 957ea04, which has an X next to it:
https://travis-ci.org/sympy/sympy/builds/9332240
which fails. This needs to get fixed, so that we can merge it.

Yes, this is the idea behind issue 1941, which is very often brought
up, but it's very hard.

Sorry, but some powers automatically denest:
In [6]: print sqrt(x/2)
sqrt(2)*sqrt(x)/2
so it is impossible to pull them together.
expand_log does what you want, though it also expands using the
additive rule. It's not too much more complicated to make it work with
a multiplication of powers
In the attached file there is a new version of ``descent``; I followed your
suggestion about
reducing the input to the square free part; in this way the lowest modular
square root is
always used; there is no need to use others; so the code in Smart seems to
be correct,
provided the input is
10 matches
