The pain rule
The chain rule is fantastic. Avoiding it is the Pain rule.
In one of the homework, you had to compute the derivative of (1+x2 + x4)100.
Foiling things out gives a polynomial but is painful as the Mathematica output of
(1+x^2+x^4)^(100)illustrates. The derivative is simply 100 (1+x2+x4)99 (2x+4x3). |
