TWC - Sharing Secrets
The cache is not at the posted coordinates. To obtain the coordinates, solve the puzzle below.
Adi Shamir created an algorithm using polynomial equations to split up a secret into multiple parts such that all parts are required to reconstruct the original secret. This system is called Shamir’s Secret Sharing algorithm.(3,-5363)
To find the final coordinates, you will be required to reconstruct 2 quadratic equations and find their vertical intercepts given 3 points on the curve. (1,912)
South
Given the points (1,-13) and (2,-1860) construct a quadratic equation in the form ax2+bx+c
East
Given the points (2,2203) and (3,4400) construct a quadratic equation in the form Ax2+Bx+C
The final coordinates are
S 37° 30.c' E 145° 10.C'
