Witryna15 paź 2009 · Sec(2x) = 1/Cos(2x) Integral of sec2x-cosx plus x2dx? I wasn't entirely sure what you meant, but if the problem was to find the integral of [sec(2x)-cos(x)+x^2]dx, then in order to get the answer you must follow a couple of steps:First you should separate the problem into three parts as you are allowed to with integration. WitrynaHence, the formula of sin square x using Pythagorean identity is sin^2x = 1 - cos^2x. This formula of sin^2x is used to simplify trigonometric expressions. Sin^2x Formula in Terms of Cos2x. Now, we have another trigonometric formula which is the double angle formula of the cosine function given by cos2x = 1 - 2sin^2x. WitrynaSo what you have done is apparently wrong. The equality you used is true, the problemes lies elsewhere. In fact when you add the two terms you found : A =\frac{\cos^2x}{\cos^2x+4\sin^2x} B =\frac{\sin^2x}{\sin^2x+4\cos^2x} ... moebius bedetheque
