第一題:Suppose that f(x+y)=f(x)f(y) for all x and y. Show that if f'(0) exist
than f'(a) exist and f'(a)=f(a)f'(0)
第二題:Find the equation of the tangent line to y=tanx at x=0
第三題:y=(2x-3)/(x^2+4)^2 find Dxy
第四題:G'(1) if G(t)=(t^2+9)^3*(t^2-2)^4
第五題:G'(1/2) if G(s)=cos拍s*sin^2拍s
第六題:Find d^3y/dx^3 (好像是微分三次的意思) y=sin(7x)
先降子好了...有的話我在問
