I think these are bugs in parse_expr. Sorry, my python expertise is
insufficient to determine what is going on.
In [80]:
transformations=standard_transformations+(convert_xor,implicit_multiplication_application)
In [81]: parse_expr("sin^2 (3x*E^(x))", transformations=transformations)
Out[81]:
⎛ ⎛ x⎞⎞
⎜ ⎝2 ⎠⎟
sin⎝3⋅x⋅ℯ ⎠
In [82]: parse_expr("sin^2 (3*E^(x))", transformations=transformations)
File "<string>", line 1
sin (Integer (3 )*(E (Symbol ('x' )))**Integer (2 )**)
^
SyntaxError: unexpected EOF while parsing
In [84]: parse_expr("sin**2(E^(x))", transformations=transformations)
Out[84]:
⎛ ⎛ x⎞⎞
⎜ ⎝2 ⎠⎟
sin⎝ℯ ⎠
In [85]: parse_expr("sin**2(E^(3x))", transformations=transformations)
