Help for sec.2.6 12

(1/1)

DaiZhaoXiZhou:
my solution for 12 is c=-1/(x^2+y^2)^(1/2)
However the answer from the textbook is x^2+y^2=c
Can I write c=-1/(x^2+y^2)^(1/2) as the answer?

shiyuancao:
Your answer is not wrong. But I think it's always better if we are able to simplify as much as possible.
