① linear function: y=kx+b

② Quadratic function: y = ax 2+bx+c, etc.

Second, the derivation formulas of several common functions

①C'=0(C is a constant)

② (x n)' = NX (n-1) (n ∈ q), etc.

Three, four algorithms of derivative

① (u v)' = u v', and so on.

Fourth, the derivative function of composite function

① Let y = u (t) and t = v (x), then y'(x) = u'(t)v'(x) = u' v'(x).
