想問一些簡單的數學問題

f(X)=sinx
g(X)=asinx
h(X)=sinbx
j(X)=sin(x+c)
k(X)=asinb(x+c)

以上各題的derived function 是什麽??


我的 Derivative 不太好的說

勿罵

f'(x)=cosx
g'(x)=acosx
h'(x)=bcosbx
j'(x)=cos(x+c)
k'(x)=abcos(x+c)

我當然明白f'(x)
但是如何轉化==

Are you sure that you understand "f'(x)" ?
It is just "Calculus".
If you want to know deeply, like why the derivation of sinx is cosx,
you can derive them by the defination of the derivation from the limit.
