WebNov 5, 2015 · Help find open intervals (inc./dec.) Finding the open intervals seems easy to me except when I stumble upon trigonometry. Problem: identify intervals in which the function is increasing or decreasing f (x)=sin (x)+cos (x) [ 0, 2 π] My attempt I started with the derivative which is f' (x)=cos (x)-sin (x) then equaled it to zero. WebA closed interval notation is a way of representing a set of numbers that includes all the numbers in the interval between two given numbers. In this notation, the numbers at the endpoints of the interval are included in the set. The notation for a closed interval is typically of the form [a,b], where a and b are the endpoints of the interval.
