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
The Root Glass Company the center portion of the newly designed sample Coca-Cola bottle. With limited time remaining before the molten glass furnaces would be shut down for cleaning, Dean produced a few sample bottles that would be submitted to the national Coca-Cola bottle contest.
