(sqrt(cos(x))*cos(200x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01,sqrt(9-x^2),-sqrt(9
问题描述：
(sqrt(cos(x))*cos(200x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01,sqrt(9-x^2),-sqrt(9
答
在Google中Google函数(sqrt(cos(x))*cos(200x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01, sqrt(9-x^2), -sqrt(9-x^2) from -4.5 to 4.5 可显示出蓝色的心,只适用于Firefox,Chrome,Safari,IE9以及各类智能手机/平板浏览器,IE6,7,8是搜不出来地.
