在技术层面,polar函数用于将(r, θ)形式的极坐标转换为(x, y)形式的直角坐标。极坐标的转换公式为: [ x = r \cdot \cos(θ) ] [ y = r \cdot \sin(θ) ] 类图 下面是展示polar函数及其相关类的类图: PolarConverter+convert_to_cartesian(r: float, theta: float) 比较表 架构解析 在构建一个能...
The return value of this function is the coordinate in polar form. To view the coordinate in cartesian form, use the `to_cartesian` function. # Ignore the `to_cartesian` function in this code snippet, it simply converts polar to cartesian coordinates. NOTE: This function requires self.relati...

The algebraic form is native to Python when you specify complex numbers using their literals. You can also view them as points on a Euclidean plane in the Cartesian or polar coordinate systems. While there aren’t separate representations for the trigonometric or exponential form in Python, you ...
