Which of the following is the general solution of the differential equation dy/dx equals the quotient of 8 times x / y ?

a.)y^2 = x^2 + c

b.)x^2 - y^2 = c

c.)x^2 = 4x^2 + c

d.)y^2 = 8x^2 + c

i believe the answer is d

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
