1. The problem statement, all variables and given/known data obtain the number r = √15 -3 as an approximation to the nonzero root of the equation x^2 = sinx by using the cubic Taylor polynomial approximation to sinx 2. Relevant equations cubic taylor polynomial of sinx = x- x^3/3! 3. The attempt at a solution Sinx = x-x^3/3! + E(x) x^2 = x-x^3/6+ E(x) How do I able to obtain the r?
