Why is my question deleted as "missing context"?
I once asked a question about the integral of $(\operatorname{sech} x)^2$.
It got deleted as "missing context".

It means that teachers like to formulate their answers to meet the needs of individual students, and can't do that if we don't know anything about the student. If a question just asks, "what's the integral of $\rm{sech}^2x$?" then we don't know whether the student's problem is not knowing what $\rm{sech}^2x$ means, or not knowing what "integral" means, or any of a dozen other difficulties the student could be having. The more you tell us about what (relevent things) you know, and what you don't know, the more helpful we can be to you. –
