Fast sine/cosine/tangent approximation using fourth degree polynomials
Project description
fasttrig
A fast and lightweight approximation of sin, cos, and tan using 4th-degree polynomials.
Unit: radian
Accuracy: Error < 0.001
Example
import numpy as np
from fasttrig import P1_fast, fast_cos, fast_tan
print(P1_fast(np.pi))
print(P1_fast([0, np.pi/2, np.pi]))
print(fast_cos([0, np.pi/2, np.pi]))
print(fast_tan(np.linspace(0, 2*np.pi, 100)))
