(Follows from the mean value theorem.) • (b) False. (For example, /(x) ... Apr 28, 2015 ... Use the Pythagorean Identity sin 2 x + cos 2 x = 1, so sin 2 x = 1-cos 2 x sin x = sin 2 x/sin x sin x = sin x Nov 7, 2013 ... The trick is to use Then your integral becomes From this we get Substituting in the latter integral , this is immediately integrated to. Let's prove the given trigonometric identity. Step 1: Rewrite the given expression. The given expression is: cosec(x) - cot(x) / 1 - cos(x).
