## Homework Statement

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

## Homework Equations

cubic taylor polynomial of sinx = x- x^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?
