Splet08. maj 2024 · Lastly, note that x ↦ π − x preserves ( sin x + 1 2 + sin 2 x) but negates cos ( x). So f ( π − x) = − f ( x). And this means that f takes negative values just as it takes positive values. That is, − 1 is in the range, but not − 2 or anything smaller. So the integers in the range of f make up the set { − 1, 0, 1 }. Share Cite Follow Splet16. okt. 2015 · Find the absolute extrema of the given function f (x) = sin x + cos x on interval [0, 2π]?
