2. Vite's formula is the following infinite product of nested radicals representing the mathematical constant 71: 2_V2 V2+ v2 V2+V2+ v2 TC 2 2 2 Write a Scheme function named (viete n) which approximates using Vite's formula. Note: You may want to use a helper function that takes an additonal parameter so that you can compute the numerator of each term easily (in a let form perhaps) as well as pass it to the recursive call
