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

Bisphosphonates were first developed in the nineteenth century. They were first investigated for use in disorders of bone metabolism in the 1960s. They are now used clinically for the treatment of osteoporosis, Paget's disease, bone metastasis, multiple myeloma, and other conditions that feature bone fragility.

Many of the drugs used by neuroscientists are derived from toxic plants and venomous animals (such as snakes, spiders, snails, and puffer fish).

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.
