You are using the notation used by
numeric::int
instead of that to
int
Take a look at their differences in the documentation: they might seems the same, but they are not.
doc numeric::int
doc int

Hi,
that's the maple notation. Use the following:
syms x
S=int(sin(cos(x)), x, 0, 1)
Then it should work, although there is no (symbolic) solution to this ...

This gives me the error "Cannot integrate with respect to '0'. The integration variable must be a symbolic variable."
