Cube root polar angle by three in order to define a cube root. With this definition, the principal cube root of a negative number is a complex number, and for instance will not be −2, but rather . This difficulty can also be solved by considering the cube root as a multivalued function: if we write the original complex number "x" in three equivalent forms, namely The principal complex cube roots of these three forms are then respectively Unless , these three complex numbers are distinct, even though the three representations of "x" were equivalent. For example, may then be calculated to
Cube (film series) the maze, while also trying to solve the mystery of what the cube is and why they are in it. However, the pressure of being in the Cube generally turns one of the prisoners into a homicidal maniac who preys on the others. "Cube Zero" was slightly different from the first two films in that it also dealt with the people on the outside of the Cube whose job it was to control the cube and oversee those within. A fourth film was rumored in March 2011, and a remake of the first film was announced in April 2015. In
