Hey I'm looking for the download for the maths problem-solving program shown in this post

The paddock has a radius r_p given by:



Now, you want the goat to eat half a square unit of grass, or equivalently, to leave half a square unit of grass uneaten. Assuming the goat can traverse the entire circumference of the paddock, the uneaten grass will be a small circle in the centre of the paddock. Ok, we have a picture in mind now.

The circle whose area is half a square unit has radius r_u given by



We want the length of the lead to be:

Is it a program or are people jsut using crazy coding?

They are using what is called a type-setting system, known as LaTeX. You will notice a button above the quick reply box that says "Launch LaTeX Equation Editor". If you click on it, you will be able to access the editor.
