SUMMARY
The extended product rule for derivatives allows differentiation of functions with three or more terms. The standard product rule is expressed as (uv)' = uv' + u'v, where u and v are functions. For three functions, the derivative is given by (uvw)' = (uv)'w + (uv)w' = u'vw + uv'w + uvw'. This formula can be extended to four or more terms, facilitating the differentiation of complex products efficiently.
