Question 1 second and third part and secondly i want to know for first part i am getting (x^2-y^2)dy/dx=2xy but i dont know why the answer key has double differentiated it
Is it correct?
Can you tell fourth part too if possible
In the first part , you will get 2 arbitrary constants;
one for the radius and the other for the coordinates of the centre of the circle.
So it is differentiated twice.
I understood my mistake i got the answer thanks for your working
