Cos Theta is one of the six trigonometric functions. It is defined by the ratio of the adjacent side to the hypotenuse of the triangle where theta is an acute angle.
The tangent double angle formula states that for an angle 'y', tan 2y = 2 tan y/{1-tan^(2) y}. What is sin 2x double angle? The double angle formula is used to calculate sin 2x, cos 2x, tan 2x, for any given angle 'x'. The sine double angle formula for an angle 'x' ...

可以直接定义\[{{\text{e}}^{\text{i}\theta }}\equiv z\left( \theta \right)=\cos \theta +\text{i}\sin \theta \]吗? 其实不太行. 因为指数映射\[{{\text{e}}^{x}}\equiv \sum\limits_{n}{\frac{{{x}^{n}}}{n!}}\]这个符号已经被定义过了, 所以现在就是要证明这俩定义相容....
