Question

help< i need help with a 3d grapher, i am using www.romanlabs.com I cannot figure out the code how to graph simple curves like f(x,y)= x^2 + y^2

Answer 1

can you see rotations using this program

Answer 2

im not sure, i cant graph even the most basic of basic functions

Answer 3

is it free

Answer 4

yes of course

Answer 5

its a 30 day trial ,

Answer 6

it just looks like it has a sweet interface and what not , its a shame i cant figure it out

Answer 7

looks good, i will try it

Answer 8

where do you enter the equations

Answer 9

go to graph in the menu, and press ADD function graph

Answer 10

then how do you enter the functions

Answer 11

thats as far as i got, lol

Answer 12

what a strange program ,

Answer 13

man it look o cool, but i guess i need to read the instructions

Answer 14

where are they?

Answer 15

i cant find them

Answer 16

it would be cool to see rotations about the x and y axis

Answer 17

yeah, doesnt seem to rotate
but you can type y = sin u

Answer 18

but it should

Answer 19

oh i get it, its like parametric

Answer 20

ok so let x = u, y = sin (u)

Answer 21

but where do i type in y=sin(u)

Answer 22

press Ctrl+F

Answer 23

okay

Answer 24

then where do i go

Answer 25

where it says x(u,v,t) = u
y(u,v,t) = sin u

Answer 26

use parenthesees

Answer 27

sin(u)

Answer 28

hey that is too cool, try rotating the graph

Answer 29

ok i found it

Answer 30

F6

Answer 31

let me see if i can get like a circle or cone

Answer 32

have you found out how to enter that equation, you posted

Answer 33

yes now i can
x(u,v,t) = u
y(u,v,t) = v
z(u,v,t) = u^2 + v^2

Answer 34

yup

Answer 35

ok, , thats cool

Answer 36

yes that one is

Answer 37

what math are you working on?

Answer 38

calc of two variables

Answer 39

man, but i dont think it generates 3D rotation

Answer 40

it does
there should be a clockwise arrow in the pane above

Answer 41

yeah but if i enter like x^2 or something, i wanted to see like a 3D anmination of the cone it hould produce when rotated about the y axis. But its still easier to imagine it using this program

Answer 42

maybe if i plot points

Answer 43

i dont think it can rotate like what youre thinking

Answer 44

like upside down revolving

Answer 45

how can i create those 3d graphs from the graph gallary page

Answer 46

well you can create the z = u^2 + v^2

Answer 47

i wanna create these grpahs: http://www.romanlab.com/3dg/graphs.htm

Answer 48

yeah, its like you have to figure it out from scratch

Answer 49

i will play around with this program and see what i do, but for the momement it seem really similar to graphmatica

Answer 50

whats that

Answer 51

its a similar program: http://graphmatica.com/
