Edit: The code may still work but the compiler will complain because you are attempting an import from an incorrect location. I'd simply change the import based on your structure. For example:
The equilateral triangle calculator will help you with calculations of standard triangle parameters. Whether you are looking for the equilateral triangle area, its height, perimeter, circumradius, or inradius, this great tool is a safe bet. Scroll down to read more about valuable formulas (such as to calculate the height of an equilateral triangle) and learn what an equilateral triangle is.
The equilateral triangle is a special case of an isosceles triangle, having not just two but all three sides equal. If you would like to learn more about the isosceles triangle, our isosceles triangle calculator is just the tool you need.
Maybe that's a bit too much calculation to do by hand or calculator. You'll be glad to know what we have an applet that will do the grunt work for you. In the following applet, you can type in the values of the parameters and the values of the initial conditions for the discrete SIR model, and it will evolve the dynamical system for you. (At least it will calculate and plot the first 500 time steps.) 153554b96e
