Two differential equations representing the family of circles touching \(y-\) axis at the origin is: |
Linear and of the first order Non-Linear and of the first order Linear and of second order Non-Linear and of second order |
Linear and of the first order |
circle touching y axis at origin $(x-a)^2+y^2=a^2$ $x^2-2ax+y^2=0$ ...(1) differentiating wrt x $2x-2a+2yy'=0$ $x-a+yy'=0$ $x+yy'=a$ ...(2) putting 'a' from (2) in (1) $x^2-2(x+yy')x+y^2=0$ $x^2-2x^2-2xyy'+y^2=0$ $y^2-x^2-2xyy'=0$ linear first order |
