推 ERT312 : consider g(x)=f(x)/x 11/04 20:31
→ kuromu : there exists c∈(a,b) s.t. g'(c)=0 11/05 04:05
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
