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).
