WebThe arctan function is the inverse of the tan function. One way of remembering what it looks like is to remember that the graph of the inverse of a function can be obtained by reflecting it through the straight line y = x. The two functions are shown in the figure below. The graph of arctan (x) (the blue dashed line) can be obtained by ... Web10 Feb 2024 · Explanation: The series: ∞ ∑ n=0 1 (n +1)(n +2) has positive terms, so we can use the direct comparison test identifying another convergent series: ∞ ∑ n=0bn such that: 1 (n +1)(n + 2) < bn for n > N. Now note that clearly, for n > 1: (n +1) > n ⇒ 1 n + 1 < 1 n and also: (n +2) > n ⇒ 1 n + 2 < 1 n and multiplying the two inequalities:
