１）if a rectangle has its base on the x-axis and two verices on the curve Y=e^(-x^2),show that the rectangle has the largest possible area when the

two verices are at the points of inflection of the curve.

 

2) Find the highest and lowest points on the curve X^2+XY+Y^2=12

 

3)find the point on the parabola Y=1-X^2 at which the tangent line cuts

from the first quadrant the triangle with the smallest Area.

谢谢大家!

我也知道啊,我自己最近也在准备杀G,没办法,别人找上门,我不好意思推.可是不碰数学好多年了,最近脑袋里都想的是G的数学,对她的PROJECT完全没思路,所以才不得以发到这里麻烦大家,真的很不好意思.
