In this video, we are going to derive value of 1 + cosine of 2x.The identity cos(2x) has been explained in the following videohttps://youtu.be/NTgX1EY6Poo#co cos2X=(cosX)^2-(sinX)^2=2*(cosX)^2-1=1-2*(sinX)^2. 即：cos2x=2cosx的平方-1=cosx的平方-sinx平方=1-2sinx的平方. cos2x的函数图像： 扩展资料. 三角函数一般用于计算三角形中未知长度的边和未知的角度，在导航、工程学以及物理学方面都有广泛的用途。 This video works through the Limit of (cos x - cos 2x)/(x^2). This type of limit is typically found in a Calculus 1 class.#mathematics #calculus #limits**** I will say that (cos (2x)) 2 means: First calculate 2x, then find cosine of that and finally square that result. Notice that it is still 2 x, not 4x. The fact that 2 is outside the parentheses means that it only applies to the final result.
