Catenary / Parabola Curve Calculator (https://drive.google.com/file/d/0BwE-L0KzzInzSkVSY2Q2ZXBMWXc/edit?usp=sharing)

So I have used various curve generators in the past successfully after getting use to how they function. Over the past projects I have repeatedly tweaked them until I have finally ended up with a condensed ultra simple version. This will generate your basic catenary/parabola curves needed for cat-cut-tarps and bridge hammocks. And to the math experts, yes, I know it is not an exact parabola or catenary curve but I am confident that it is more than accurate enough for hammock and tarp applications. :)

With this calculator/generator you only need to input the length of the curve and the desired depth of the curve. It will output the x and y cords for the curve. The Y cords is the length of the curve in increments of 1 and the x cords adjacent to it are the measurements for the depth of the curve.

I hope this curve generator/calculator comes in as handy for someone else, as it has been for me on my projects. I tried to upload it to the site but the site only accepts xls docs and not xlsx docs which is the newer versions of excel docs. I didnt want to save in the old format because it would lose some of the conditional formatting. I have also uploaded this to my google docs so if you dont have Microsoft excel you can still use it on google.

Here are the two links.
