Show that if x and y are real numbers, x2 + y2 >= 2xy and (x + y)2 >= 4xy; When does equality hold (with proof)? Show that if x and y are real numbers, x2 + y2 2xy and (x y) 2Hry. When does equality hold (with proof)?
f(x, y) = x2 + y2 + 2xy + 6. 1- Find all the local extremas and 2) does the function f have an absolute max or min on R2
2. A) Calculate the work done by the field } = (x² - y2,-2xy) when moving an object from the origin to the point (1, 2) along the path C: x = t?, y = 2t. B) Use a Theorem from 16.3 to determine whether or not F = (x2 - y2,-2xy) is a conservative vector field. C) Deduce the work done by the field } = (x2 - y2,-2xy) moving an object from the point (1, 2) to the...
