球坐标

rho=20*t^2

theta=60*log(30)*t

phi=7200*t

rho=200*t

theta=900*t

phi=t*90*10

圆柱坐标

r=5+0.3*sin(t*180)+t

theta=t*360*30

z=t*5

正弦曲线

笛卡尔坐标系

x=50*t

y=10*sin(t*360)

z=0

螺旋线(Helical curve)

圆柱坐标

r=t

theta=10+t*(20*360)

z=t*3

i don't know this is what you want to have,i have more equation of curves! [email protected]
