d^3/4(d^1/4-d^-1/4)

Solution for d^3/4(d^1/4-d^-1/4) equation:

D( d )

d = 0

d = 0

d = 0

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

((d^3)/4)*((d^1)/4-((d^-1)/4)) = 0

((d^3)/4)*(d/4-((d^-1)/4)) = 0

1/4*d^3*(1/4*d-1/4*d^-1) = 0

1/4*d-1/4*d^-1 = 0

1/4*d^-1*(d^2-1) = 0

1*d^2 = 1 // : 1

d^2 = 1

d^2 = 1 // ^ 1/2

abs(d) = 1

d = 1 or d = -1

1/4*d^-1*(d-1)*(d+1) = 0

1/4*1/4*d^-1*d^3*(d-1)*(d+1) = 0

( 1/4*d^-1 )

1/4*d^-1 = 0 // : 1/4

d^-1 = 0

d należy do O

( 1/4*d^3 )

1/4*d^3 = 0 // : 1/4

d^3 = 0

d = 0

( d+1 )

d+1 = 0 // - 1

d = -1

( d-1 )

d-1 = 0 // + 1

d = 1

d in { 0} 

d in { -1, 1 }
