转换为三角函数形式 cot(theta)+tan(theta) cot(θ)+tan(θ)cot(θ)+tan(θ) 这是复数的三角函数形式,其中|z||z|是模数,θθ是复平面上形成的夹角。 z=a+bi=|z|(cos(θ)+isin(θ))z=a+bi=|z|(cos(θ)+isin(θ)) 复数的模是复平面上距离原点的距离。
a_1 + \cdots + a_n = (-\mathrm{i}) \left( n + \frac{2n(-1)^{n-1}}{(-1)^n - \mathrm{e}^{2n\mathrm{i}\theta}} \right) = \begin{cases} n\tan n\theta,& 2\nmid n\\ - n \cot n\theta,& 2\mid n \end{cases} \\a_1 \cdots a_n = (-\mathrm{i})^n ...

由已知\(2k \pi +\dfrac{ \pi }{2} < \theta < 2k \pi + \pi (k \in \mathbf{Z})\)可得\(k \pi +\dfrac{ \pi }{4} < \dfrac{ \theta }{2} < k\pi +\dfrac{ \pi }{2}\).则\(2m \pi +\dfrac{ \pi }{4} < \dfrac{ \theta }{2} < 2m \pi +\dfrac{ \pi...
本贴的目的便是将函数引入LuaSTG中,在教程中将会使用self.vx与self.vy来设置速度(因为垃圾Lua没有反三角函数),大概有一下几种形式 1速度固定型 self.vx=v*cos(a) self.vy=v*sin(a) 2横向位移速度固定型 self.vx=v self.vy=v*tan(a)=v*sin(a)/cos(a) 3纵向位移速度固定型 self.vx=v*cot(a)=...
