Inequation:
(1/(x-1))-(1/(x-2))=>(1/(x+1))-(1/(x+2))
(x^2(x+2))/(2x+3)<=0
7x<-3
(3/(x+1))<=(5/(x+2))
Identical expressions
arctg^ two (x)/n^ three <= one /n^ three
arctg squared (x) divide by n cubed less than or equal to 1 divide by n cubed
arctg to the power of two (x) divide by n to the power of three less than or equal to one divide by n to the power of three
arctg2(x)/n3<=1/n3
arctg2x/n3<=1/n3
arctg²(x)/n³<=1/n³
arctg to the power of 2(x)/n to the power of 3<=1/n to the power of 3
arctg^2x/n^3<=1/n^3
arctg^2(x) divide by n^3<=1 divide by n^3

arctg^2(x)/n^3<=1/n^3 inequation
