The expression to the left of the equals sign is not a valid target for an assignment

please tell me the problem

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."
