Sin曲线

vertices =

x = from (-*PI) to (*PI)

y = sin(x)

震荡sin曲线

vertices =

x = from (-*PI) to (*PI)

y = exp(abs(x)/)*sin(x)

极限震荡sin曲线

vertices =

x = from (-) to

y = x*sin(/x)

x = x*

y = y*

SIN曲线的变异

#http://www.mathcurve.com/courbes2d/abdank/abdank.shtml

vertices =

t = from (-*PI) to (*PI)

r =

y = r*sin(t)

x = r*r/*(t + sin(t)*cos(t))

面的形式:

vertices = D1: D2:

u = from (-PI) to (PI) D1

v = from - to  D2

x = u

y = v*sin(x)
