 Hi, and welcome to our session. Let us discuss the following question. The question says, form the differential equation, representing the function of curves y squared minus 2 Ay plus x squared equals to a squared, where a is the arbitrary constraint. So now we begin with the solution. Given equation is y squared minus 2 Ay plus x squared equals to a squared. We have learned that if the equation involves only one parameter, then we have to differentiate that equation only once. Now here, since the given equation contains only one parameter, that is a, differentiate. Let's name the given equation as 1 only once. Getting 1 with respect to x, we get a into dy by dx minus 2 a into dy by dx plus 2x equals to 0 into dy by dx.
