Graph the equation x^2+y^2+4x-6y +12=0.相关知识点: 试题来源: 解析 (x+2)^2+(y-3)^2=1 Group the expression involving x, group the expression involving y, and put the constant on the right side of the equation. The result is(x^2+4x)+(y^2-6y)=-12Next, complete the square...
First graph 4x^2+y^2=4 (x^2)/((1))+(y^2)/((44))=1 First find the y-intercepts so, substitute x=0 in the equation and you have (x^2)/((1))+(y^2)/((44))=1 ((0)^2)/((11))+(y^2)/((4))=1 (y^2)/((4))=1 y=±2 Now, find the x-intercepts so, ...
知识点窍从两个方程中消去某一变量,即可得到母线平行于该变量轴的柱面,再从两方程中消去另一变量,又可得一柱面,原曲线即为两柱面的交线2x2+y2+z2=16解题过程(1)①x2-y2+z2=0②3x2+2z2=16由①+②,②×2-①得③3y2-z2=16④柱面③,④的交线即为原曲线(2y2+(z-2)2+4x=...
