Solution for Y=x^3/x-1 equation:


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

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

Y-((x^3)/x)+1 = 0

Y-x^2+1 = 0

-1*x^2 = -(Y+1) // : -1

x^2 = Y+1

x^2 = Y+1 // ^ 1/2

abs(x) = (Y+1)^(1/2)

x = (Y+1)^(1/2) or x = -(Y+1)^(1/2)

x in { (Y+1)^(1/2), -(Y+1)^(1/2) }
