滑贝肢1127设f(x)有三阶连续的导数,且f(x+h)=f(x)+hf'(x+θh),0<θ<1中的θ与h无关,试证f'''=0 -
贺龙澜15556105233 ______ f(x+h)=f(x)+hf'(x+th) 两边对h求导得: f'(x+h)=f'(x+th)+thf''(x+th) f'(x+h)-f'(x)=f'(x+th)-f'(x)+thf''(x+th) (f'(x+h)-f'(x))/h=t(f'(x+th)-f'(x))/th+tf''(x+th) 令h趋于0,取极限得: f''(x)=limtf''(x)+limtf''(x) 所以lim(h趋于0)t=1/2

贺龙澜15556105233 ______ 由f(x+h)=f(x)+hf'(x+th) 可得f'(x+th)=[f(x+h)-f(x)]/h 对f'(x+th)泰勒展开得 f'(x+th)=f'(x)+thf''(ξ) 联立得t={[f(x+h)-f(x)]/h - f'(x)} / hf''(ξ) =[f(x+h)-f(x)-hf'(x)] / h / f''(ξ) 取极限得 lim (h->0)t =lim [f(x+h)-f(x)-hf'(x)] / h^2 * lim 1/f''(ξ) 用洛必达法则 =lim [f'(x+h)-f'(0)- f'(x)] / 2h ...

滑贝肢1127The bus we went there broke down on the way 单选
贺龙澜15556105233 ______ 选B 吧. 因为这里考察的是“介词+定语从句的先行词+定语从句结构”.而一般不用“介词+that ＂结构!that 引导定语从句时无意义.选which 时缺介词!选A错的理由是＂by +n＂时不加the .你看见过＂by the bus＂吗?
