The Curve Archive



Some curves I hacked up for X11...

x = t * cos(t), y = t * sin(t)


r = a * sin(t) / t


x = (a+b) * cos(t) - b * cos((a/b +1) * t)
y = (a+b) * sin(t) - b * sin((a/b +1) * t)


r = a * 1/cos(4*t) a=.5


x = (a+b) * cos(t) - c * cos((a/b +1) * t)
y = (a+b) * sin(t) - c * sin((a/b +1) * t)


r = a * exp(b*t) a=1, b=.1


r = pow (t,a) a=.5



r = a * (1 + 2*sin(t/2))


r = sqrt( pow(a,2) * cos(2*t)) a=10


To get this shape I rotated a lemniscate 360 degrees in 15 degree increments


x = a * sin( n*t+c ) a=5, b=6, c=7, n=4
y = b * sin(t)


r = 1/sqrt(t) * 7


r = log(t)


r = a * sin( k*t ) a=10, k=7


r = ((5 * cos( 4*t)) / a) a=.5


r = a * cos(t) * (4 * pow( sin(t), 2) -1)
