Web2. Saying sin ( 3 x) = 0 means 3 x = k π, for some integer k. Therefore x = k π / 3 and you just have to determine all integers k such that k π / 3 ∈ [ − π, π]. Now. − π ≤ k π 3 ≤ π. is equivalent to. − 3 ≤ k ≤ 3. so we have seven critical points. For telling apart the points of maximum and minimum, the simplest way is ... WebJul 9, 2024 · Here’s how: Take a number line and put down the critical numbers you have found: 0, –2, and 2. You divide this number line into four regions: to the left of –2, from –2 to 0, from 0 to 2, and to the right of 2. Pick a value from each region, plug it into the first derivative, and note whether your result is positive or negative. pin word document to start menu windows 10
