Hi,

I apologize if I have this posted in the wrong section of the forum.

I need assistance in solving multiple simultaneous equations. I don't mind doing the hard work, I just need to be pointed in the right direction. Right now I don't have a clue how to solve this. I am a biologist and still have a lot to learn in maths.

Here is the problem:

X Y A

0.541856 0.171848 5

0.732858 0.402196 25

0.838236 0.597253 50

0.926462 0.797811 75

0.983306 0.950288 95

0.999894 0.999673 100

I have a relationship between X and Y, but I know that along certain points on that curve there are the values A.

So what I need to find is the equation which relates X and Y to equal A.

But I don't know where to start. I know this isn't a linear equation, and after that I'm stuck.

Any help would be greatly appreciated.

Cheers
