sin^ two ((one hundred and eighty -x)/(4k+ two))-(one -cos(x))/ seventy-two = zero
sinus of squared ((180 minus x) divide by (4k plus 2)) minus (1 minus co sinus of e of (x)) divide by 72 equally 0
sinus of to the power of two ((one hundred and eighty minus x) divide by (4k plus two)) minus (one minus co sinus of e of (x)) divide by seventy minus two equally zero
sin2((180-x)/(4k+2))-(1-cos(x))/72=0
