Writhe the order and degree of the differentialequation `y=x(dy)/(dx)+a sqrt(1+((dy)/(dx))^2)dot` |
|
Answer» The given equation may be weitten as `sqrt(1+((dy)/(dx))^(2))+(y-x(dy)/(dx))` `implies 1+((dy)/(dx))^(2)=(y-x(dy)/(dx))^(2)" "["on squaring both sides"]` `implies1+((dy)/(dx))^(2)=y^(2)+x^(2)((dy)/(dx))-2xy(dy)/(dx)` `implies(1-x^(2))((dy)/(dx))^(2)+2xy(dy)/(dx)+(1-y^(2))=0.` Clearly, it is a differential equation of order = 1 and degree =2. |
