Our half-circle can be thought of as a function y=f(x), where x - is the coordinate along the abscissa axis, and y is the function equal to the value of the corresponding half-circle point. At the moment it doesn't support differential dividing of the sort supported by the BS-2 dividing Below you can find two calculators which calculate how to cut a circle into equal parts - traditional and non-traditional way. We need to cut two times more for second point , three times more for third point and so on. var D=new Date(),d=document,b='body',ce='createElement',ac='appendChild',st='style',ds='display',n='none',gi='getElementById'; I was wandering around the web last night, looking for some pulley-to-pulley ratio calculators, and I found a great circle index calculator that could be helpful lining up basket illusion bowls or creating your own index wheel for other projects. Depending on the number, these sectors have a certain angle. The antiderivative of our function is : We need to find the value of constant. Only works when increments divide evenly. Two ways to cut a circle into equal parts : sector cuts and parallel cuts. Please read AddThis Privacy for more information.
