# How to convert the results of point doubling (Rx1 and Ry1) to point addition (Rx2 and Ry2) without knowledge of Qx and Qy

I'm working with the secp256k1 elliptic curve and have point doubling and point addition formulas for this curve. Given the following formulas:

s = (Qy - Gy) * pow(Qx - Gx, -1, p) % p
Rx = (s**2 - Qx - Gx) % p
Ry = (s * (Qx - Rx) - Qy) % p


Point Doubling Formula in Python3:

s = (3 * Qx**2) * pow(Qy*2, -1, p) % p
Rx = (s**2 - Qx*2) % p
Ry = (s * (Qx - Rx) - Qy) % p


If a point is given Qx and Qy

Qx = 112711660439710606056748659173929673102114977341539408544630613555209775888121
Qy = 25583027980570883691656905877401976406448868254816295069919888960541586679410


performing point doubling on the given points (Qx, Qy) will get the below output

Rx1 = 115780575977492633039504758427830329241728645270042306223540962614150928364886
Ry1 = 78735063515800386211891312544505775871260717697865196436804966483607426560663


Performing point addition on the given points (Qx, Qy) will get

Rx2 = 103388573995635080359749164254216598308788835304023601477803095234286494993683
Ry2 = 37057141145242123013015316630864329550140216928701153669873286428255828810018


Now, I'm looking for a way to convert (Rx1, Ry1) to (Rx2, Ry2) without knowing the original given values (Qx, Qy). Is there a method or algorithm to achieve this conversion?
