具体来说，当θ=0时，cos(θ)取得最大值1，表示单位圆上x轴正半轴上的点。当θ=π（即180度）时，cos(θ)取得最小值-1，表示单位圆上x轴负半轴上的点。当θ取其他值时，cos(θ)的值会在-1和1之间变化。例如，当θ=π/2（即90度）时，co...

\theta = \omega t = \frac{2\pi}{T}t(2.21) 可知,该复变函数可以看做是一个角速度为 w 周期为T在复平面上绕原点旋转的半径为1的圆。将公式代回到复变函数中,那么,复变函数可以写成公式2.22的形式 e^{\text{jω}t} = cos\omega t + jsin\omega t\text{ }(2.22) 设一组三角函数,其频率...
