Evaluate the expression cos − 1 sin 5 π 6
WebNov 1, 2015 · cos( 5π 6) = −cos( π 6). cos( π 6) = √3 2 can be seen from the geometry of a 30,60,90 degree triangle, which is half of an equilateral triangle. Therefore, cos( 5π 6) = … tan and arctan are two opposite operations. They cancel each other out. Your … Web1 5 3 √ x−1 dx also diverges. You must get the inequality in the right direction! It is also true that 1 5 3 √ x−1 ≤ 1 √ x for x≥1. This, however, is useless: since Z ∞ 1 1 3 √ x dxdiverges, this inequality tells you nothing about Z ∞ 1 1 5 3 √ x−1 dx. 44.
