I'm having some issues understanding this... Following works as
s is the variable in time. a is a parameter.
Integrate[1/(s + a), s]
gives Log[a + s]
But the following gives the integral itself.
Integrate[1/(s[t] + a), t]
If the function that needs to be integrated w.r.t time is 1/(s[t] +
a), how do I accomplish that? It seems like if integrate it wrt to s
[t] it will work.
Integrate[1/(s[t] + a), s[t]]
But does that sound about right?
Any thoughts appreciated.
