WebI will assume you intend the integrand to be interpreted as [ (2 - sin 2x) / (1 - cos 2x) ]eᵡ. To solve the integral, we will first rewrite the sine and cosine terms as follows: I) sin (2x) = 2sin (x)cos (x); II) cos (2x) = 2cos² (x) - 1. Rewriting yields 2 - sin (2x) = 2 - 2sin (x)cos (x) = 2 [1 - sin (x)cos (x)], and 1 - cos (2x) WebA反思领悟1.函数f(x)=Atan(x+)周期的求解方法(1)定义法.(2)公式法:对于函数f(x)=Atan(wx+φ)的最小正周期Tπω(3)观察法(或图象法):观察函数的图象,看自变量间隔多 … WebIf you want any….
