Find absolute max and min multivariable
WebAug 18, 2024 · Its derivative is g ′ (x) = 2x(x + 2)(2x − 1) so we have to compare g(0) = 1, g(1 / 2) = 13 / 16, plus the values at the extreme points g( − 1) = − 2 and g(1) = 1 . We may conclude that the absolute maximum point is (1, 0) and the absolute minimum point is ( − 1, 0). Alternative way: if x2 + y2 ≤ 1 then − 1 ≤ x3 ≤ x2 and 0 ≤ y4 ≤ 2y2. WebTherefore f (4) = 10 is the absolute maximum and f (1) = 0 is the absolute minimum. (b) We have g ′ ( x ) = 1 + 2 cos x. g ′ is never undefined, and we see it is zero when cos x = − 1 2 . This is a special cosine value, and thinking about the unit circle the only x in [0 , π ] for which this is true is 2 π 3 .
