I used the way that u said and it worked

## not pdf...

that is not pdf,I have it in x,y plane I want to get x,y points.

maybe I cannot say correctly

1.I have a line or curve

2.I want to put it in a x,y plane

3.getting the x,y point from that like x1,y1   x2,y2  ,...

my aim is to get nodes from line which I do not have the function but I have it in x y plane like that picture.

I do not know whether maple can do that or not.

thanks a million

it works

thank everybody but I think you did not get my mean

y1 := 2*a*b^2-b+c-d-1 = X;
y2 := a^4+b^3-b^2+c-d+2 = 0;
y3 := a*b^2-b+c-d-3 = 0;
y4 := a^3*b^2-b+c-d^3+4 = 0;
fsolve({y1, y2, y3, y4},{a,b,c,d})

I want to get the answer a b c d which should be in this way as an example

a=123+X

b=456-X^2     c=...      d=....

X or something like G H .. that are in equations are not variable just fixed parameter which we dont know them

fsolve assumes X as a variable which is not

I cannot understand maple that a b c d are just variables and X is not

## Mr.Robert Israel After that,I should us...

After that,I should use the answer in another equations and solve 6 diff equations

so its better to change the way of my project

and ignore the way which cause to this 4 equations

u and w is not important here

u can assume that such as parameter A

just 4 vars Mr Nr  Mteta Nteta are our variables

the answer of vars are not number so I cannot use fsolve
