n*Abs((- one + cos(pi/n^ two))/(- one + cos(pi/(one + n)^ two)))/(one + n)
n multiply by Abs(( minus 1 plus co sinus of e of ( Pi divide by n squared )) divide by ( minus 1 plus co sinus of e of ( Pi divide by (1 plus n) squared ))) divide by (1 plus n)
n multiply by Abs(( minus one plus co sinus of e of ( Pi divide by n to the power of two)) divide by ( minus one plus co sinus of e of ( Pi divide by (one plus n) to the power of two))) divide by (one plus n)
