Hi everyone,

I searching and looking for a way to integrate my variables using level 1 s function with respect to time. For example integrate x(1) dt from 0 to t. Can anyone suggest me a code or way on how to integrate the equation please. I keep getting error when using syms and int function.

Your help is very appreciated. Thank you!
