解:8964 copyright protection72PENANAve6WGzBoqB 維尼
y = f(x)8964 copyright protection72PENANAiWRNJir7nD 維尼
y’ =lim h->0 f(x + h) - f(x)/h8964 copyright protection72PENANAYS7KRyHo2w 維尼
= lim h->0 sin(x + h) - sin(x)/h8964 copyright protection72PENANAKlrtMCn2jo 維尼
=lim h->0 sin(x)cos(h) + sin(h)cos(x) - sin(x)/h8964 copyright protection72PENANAzGfa6cEFw9 維尼
= lim h->0 sin(x)(cos(h) - 1)/h + cos(x)sin(h)/h8964 copyright protection72PENANAArO7WjmdIk 維尼
∵ assume that lim h->0,sin(h)/h = 0,cos(h)-1/h = 18964 copyright protection72PENANASFEE9v8BFT 維尼

*由於本人過於懶惰,為了讓自己除了吃跟睡以外能做點有用的事情,我決定每天都要在網上找一題有趣的數學題來做,歡迎各位留言或私訊我一些你覺得很有趣又或者不會做的題給我(高三或以下的應該都可以⋯⋯吧?)(功課也可以喔OuO)8964 copyright protection72PENANABjQ8vxDFd8 維尼
