No because c wasn’t defined in the first place u can leave it as c
Original post by abacusabc
when you are solving a differential equation, and you have the -c which can be any value, if you are multiplying or dividing which would affect the c could you still call this c
would you have to adjust eg calling it 2c as the c can be any value

It depends, has the question provided you with x and y values?

It depends, has the question provided you with x and y values?
differential equation: (y^2)/2 = k (x^2)/2 +c
simplified (mark scheme) y^2=kx^2 + c
to sub in (0,5) to find c
mark scheme answer = 12.5
Not sure what your question is , but if you sub x=0 and y=5 you will end up with the left hand side being 25/2, which is 12.5. Therefore c = 12.5
