Hello group,
I have a request from a customer to draw a specific parabola curve described as follows: Y=X squared / 4P. Where P = 6.
Anybody knows how to do that?
Thanks,
Jeannette

select a value for x calculate y X=-1 P=6 Y=(x*x)/(4*P) Y=(-1*-1)/(4*6) Y=1/24
X=0 P=6 Y=(x*x)/(4*P) Y=(0*0)/(4*6) Y=0/24 Y=0
X=1 P=6 Y=(x*x)/(4*P) Y=(1*1)/(4*6) Y=1/24
X=2 P=6 Y=(x*x)/(4*P) Y=(2*2)/(4*6) Y=4/24
so the command is draw single point enter the location if x=1 then 1,1/24 if x=2 then
2,4/24 if x=3 then 3,9/24 etc. connect the dots with polyline arcs. the closer the dots to each other the more accurate the curve.Bob
or connect the dots with a spline
Hello,
There is a a little program (20 years old) to draw parabolic curves at
Martin
There is also a program called Z-grapher (freeware) which will do any functional, parametric or polar graph, and can export to a rastered format by copying and pasting. For this, I use Irfanview. ________________________________________ Everyone is a little krazy, but I am the kynge of krazy
