Question 1

Is the origin a critical point of the function  f(x, y) = x2 + xy + y2? If so, classify it.
◦ yes, a local maximum
◦ yes, a saddle point
◦ yes, a local minimum
◦ no

Question 2

Find and classify the critical points of the function  f(x, y) =  x sin y.
◦ local minima at  (0, nπ)  for nonzero integers n, saddle point at  (0, 0)
◦ saddle points at all points   (0, nπ)  for integers  n
◦ only critical point is  (0, 0),  a saddle point
◦ local maxima at  (0, nπ)  for even integers  n,  local minimum at  (0, nπ)  for odd  integers  n
◦ local minima at  (0, nπ)  for even integers  n,  local maximum at  (0, nπ)  for odd  integers  n

Certain rare plants containing cyanide include apricot pits and a type of potato called cassava. Fortunately, only chronic or massive ingestion of any of these plants can lead to serious poisoning.

Patients should never assume they are being given the appropriate drugs. They should make sure they know which drugs are being prescribed, and always double-check that the drugs received match the prescription.

Did you know?

Adults are resistant to the bacterium that causes Botulism. These bacteria thrive in honey – therefore, honey should never be given to infants since their immune systems are not yet resistant.

Did you know?

Though the United States has largely rejected the metric system, it is used for currency, as in 100 pennies = 1 dollar. Previously, the British currency system was used, with measurements such as 12 pence to the shilling, and 20 shillings to the pound.

Did you know?

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.
