suppose that function f(x) is continuous on [a,b]and differentiable on (a,b),and 0<a<b. If. f(a)=ka f(b)=kb. for some k show that there exists c∈(a,b) s.t. the tangent line of y=f(x) at c passes through the origin 不太會解這個 煩請各位大大幫忙 手機排版請見諒 ----- Sent from JPTT on my InFocus M330. -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 27.245.128.201 ※ 文章網址: https://www.ptt.cc/bbs/Math/M.1446631850.A.10B.html
