六⋅一儿童节,小文到公园游玩。看到公园的一段人行弯道MN(不计宽度),如图,它与两面互相垂直的围墙OP、OQ之间有一块空地MPOQN(MP⊥OP,NQ⊥OQ),他发现弯道MN上任一点到两边围墙的垂线段与围墙所围成的矩形的面积都相等,比如：A. B. C是弯道MN上的三点,矩形ADOG、矩形BEOH、矩形CFOI的面积相等。爱好数学的他建立了平面直角坐标系(如图),图中三块阴影部分的面积分别记为S1、S2、S3,并测得S2=6(单位：平方米).OG=GH=HI.

(1)求S1和S3的值；
(2)设T(x,y)是弯道MN上的任一点，写出y关于x的函数关系式；
(3)公园准备对区域MPOQN内部进行绿化改造,在横坐标、纵坐标都是偶数的点处种植花木(区域边界上的点除外)，已知MP=2米，NQ=3米。问一共能种植多少棵花木?
反比例函数的应用．
（1）判断出弯道为反比例函数图象的一部分，设函数解析式为y=
k
x
（k≠0），OG=GH=HI=a，然后表示出AG、BH、CI，再根据S2列出方程求出k，然后分别求解即可；
（2）根据k值求解即可；
（3）求出点Q的横坐标为12，再分别求出横坐标为偶数时的y值，然后计算种植的棵数即可．
(1)∵矩形ADOG、矩形BEOH、矩形CFOI的面积相等，
∴弯道为反比例函数图象的一部分，
设函数解析式为y=kx(k≠0)，OG=GH=HI=a，
则AG=ka,BH=k2a,CI=k3a，
所以,S2=k2a⋅a−k3a⋅a=6，
解得k=36，
所以,S1=ka⋅a−k2a⋅a=12k=12×36=18，
S3=k3a⋅a=13k=13×36=12；

(2)∵k=36，
∴弯道函数解析式为y=36x，
∵T(x,y)是弯道MN上的任一点，
∴y=36x；

(3)∵MP=2米，NQ=3，
∴GM=362=18,36OQ=3，
解得OQ=12，
∵在横坐标、纵坐标都是偶数的点处种植花木(区域边界上的点除外)，
∴x=2时，y=18，可以种8棵，
x=4时，y=9，可以种4棵，
x=6时，y=6，可以种2棵，
x=8时，y=4.5，可以种2棵，
x=10时，y=3.6，可以种1棵，
一共可以种：8+4+2+2+1=17棵。
答：一共能种植17棵花木。

你在这个大三角形的右上角补一个一样的三角形，两个大三角形组合成一个大长方形。然后你延长阴影部分图案的上面个边和右边个边，与大长方形边相交，这时在大长方形右上角会出现一个新的小长方形，这个新的小长方形边长为5和20，可以证明这个小长方形面积和阴影部分是相等的，所以面积为20*5=100

极坐标换成直角坐标公式是
x=p*cos(theta)
y=p*sin(theta)
