(1)/(x-x^(3))

If (x^(2)-1)/(x)=(8)/(3) and x>1; find x^(3)-(1)/(x^(3))

tan^(-1)((3x-x^(3))/(1-3x^(2)))

Tan^(-1)((3x-x^(3))/(1-3x^(2)))=

(b) If (x^(2)+1)/(x)=3(1)/(3) and x>1 ; find x^(3)-(1)/(x^(3))

If x+ (1)/(x)=3 , then x^(3) + (1)/(x^(3)) =?

If x+(1)/(x)=3, calcuate x^(2)+(1)/(x^(2)),x^(3)+(1)/(x^(3)) and x^(4)+(1)/(x^(4))

If x_(1)x_(1)x_(3)=4(4+x_(1)+x_(2)+x_(3)) then what is the value of [(1)/(2+x_(1))]+[(1)/(2+x_(2))]+[(1)/(2+x_(3))]?

lim_(xtooo)(1+x-3x^(3))/(1+x^(2)+3x^(3))

(x^(3))/(1+x^(3))+(x^(3))/((1+x^(3))^(2))+(x^(3))/ ((1+x^(3))^(3))+......... oo

Prove that 3tan^(-1)x=tan^(-1)((3x-x^3)/(1-3x^2))
