Determine the concavity of  f(x) = cos x + sin x  on [0, 2π] and identify any points of inflection.
◦ concave up on [0, π/4) ∪ (5π/4, 2π], concave down on (π/4, 5π/4); inflection points at x = π/4 and
◦ concave down on [0, 3π/4) ∪ (7π/4, 2π], concave on (3π/4, 7π/4); inflection points at  x = 3π/4 and  
◦ concave up on [0, 3π/4) ∪ (7π/4, 2π], concave down on (3π/4, 7π/4); inflection points at x = 3π/4 and  
◦ concave down on (0, 3π/4) ∪ (7π/4, 2π), concave up on (3π/4, 7π/4); inflection points at  x = 3π/4 and  
◦ concave down on [0, π/4) ∪ (5π/4, 2π], concave up on (π/4, 5π/4); inflection points at x = π/4 and
