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
C-Cube Umesh Padval was brought in to run C-Cube Semiconductor in 1998. During the late 1990s, C-Cube was unable to repeat its runaway hits seen earlier in the decade. The company sold its DiviCom division to Harmonic Lightwaves in May, 2000 for nearly $1.7 billion. C-Cube Semiconductor (Nasdaq CUBED) was eventually sold to competitor LSI Logic in March 2001 in a stock transaction worth $878 million. LSI sold off the consumer products business (including what was C-Cube) to Magnum Semiconductor in 2007. C-Cube C-Cube Microsystems was an early company in video compression technology as well as the implementation of that technology
