1.Consider the curve c:x^(2/3)+y^(2/3)=a^(2/3) (0≦x≦a,0≦y≦a) find the point P on c so that triangle bounded by the two coordinate awes and the tangent line to c at P has maximal area. x^2 y^2 2.設橢圓----+----=1的切線與x軸相交於A點,與y軸相交於B點,(a>0,b>0)試求AB線段 a^2 b^2 長之極值? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.166.9.57
