Derivation is the process of differentiation. You don't need to know what it is, just remember the formula first.

Derivative formulas of several common functions;

① C'=0(C is a constant);

②(x^n)'=nx^(n- 1)(n∈q)；

③(sinx)' = cosx；

④(cosx)' =-sinx；

⑤(e^x)'=e^x；

⑥ (a x)' = a A Xin (ln is natural logarithm).

⑦ loga(x)'=( 1/x)loga(e)

Four algorithms of derivative:

①(u v)'=u' v '

②(uv)'=u'v+uv '

③(u/v)'=(u'v-uv')/ v^2

④[u(v)]'=[u'(v)]*v' (u(v) is a compound function f[g(x)])
