You push down on a book of inertia m resting on a table with a force directed at an angle θ away from vertical. The coefficient of static friction between book and table is μs. If θ is not larger than some critical value, you cannot get the book to slide no matter how hard you push.
What is that critical value?
answer is in terms of μs
Im not sure where to start

I had this same problem... θ > arctan(μs) is the answer, you're welcome fam.
