在高中代数学里，你学习了标准二次方程序。

Everything in algebra was boring extrapolation after that, including the quadratic equation, which I have never used in my life.
以后代数中的种种推论都很枯燥，包括二次方程序，我这辈子从未用过它。

The Circle Interpolator based on the algebra figuring, if we change only a few preset constants in the register, we can directly Interpolate a quadratic curves.
