Solution for 7/9*y-11/y equation: 


D( y )

y = 0

y = 0

y = 0

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

(7/9)*y-(11/y) = 0

(7/9)*y-11*y^-1 = 0

7/9*y^1-11*y^-1 = 0

(7/9*y^2-11*y^0)/(y^1) = 0 // * y^2

y^1*(7/9*y^2-11*y^0) = 0

y^1

(7/9)*y^2-11 = 0

(7/9)*y^2-11 = 0

DELTA = 0^2-(-11*4*(7/9))

DELTA = 308/9

DELTA > 0

y = ((308/9)^(1/2)+0)/(2*(7/9)) or y = (0-(308/9)^(1/2))/(2*(7/9))

y = 9/14*(308/9)^(1/2) or y = 9/14*(308/9)^(1/2)

y in { 9/14*(308/9)^(1/2), 9/14*(308/9)^(1/2)} 

y in { 9/14*(308/9)^(1/2), 9/14*(308/9)^(1/2) }
