Use Newton's method to find the first 5 approximations of the solution to the equation \(\displaystyle \sin{\left(x \right)}= \frac{131 x^{3}}{250} - 5\) using \(\displaystyle x_0=3\).
Using the formula for Newton's method gives \begin{equation*}x_{n+1} = x_{n} - \frac{- \frac{131 x_{n}^{3}}{250} + \sin{\left(x_{n} \right)} + 5}{- \frac{393 x_{n}^{2}}{250} + \cos{\left(x_{n} \right)}} \end{equation*} Using \(\displaystyle x_0 = 3\) and \(\displaystyle n = 0,1,2,3,\) and \(\displaystyle 4\) gives: \begin{equation*}x_{1} = (3.0000000000) - \frac{- \frac{131 (3.0000000000)^{3}}{250} + \sin{\left((3.0000000000) \right)} + 5}{- \frac{393 (3.0000000000)^{2}}{250} + \cos{\left((3.0000000000) \right)}} = 2.4050148992\end{equation*} \begin{equation*}x_{2} = (2.4050148992) - \frac{- \frac{131 (2.4050148992)^{3}}{250} + \sin{\left((2.4050148992) \right)} + 5}{- \frac{393 (2.4050148992)^{2}}{250} + \cos{\left((2.4050148992) \right)}} = 2.2405217072\end{equation*} \begin{equation*}x_{3} = (2.2405217072) - \frac{- \frac{131 (2.2405217072)^{3}}{250} + \sin{\left((2.2405217072) \right)} + 5}{- \frac{393 (2.2405217072)^{2}}{250} + \cos{\left((2.2405217072) \right)}} = 2.2276480503\end{equation*} \begin{equation*}x_{4} = (2.2276480503) - \frac{- \frac{131 (2.2276480503)^{3}}{250} + \sin{\left((2.2276480503) \right)} + 5}{- \frac{393 (2.2276480503)^{2}}{250} + \cos{\left((2.2276480503) \right)}} = 2.2275710384\end{equation*} \begin{equation*}x_{5} = (2.2275710384) - \frac{- \frac{131 (2.2275710384)^{3}}{250} + \sin{\left((2.2275710384) \right)} + 5}{- \frac{393 (2.2275710384)^{2}}{250} + \cos{\left((2.2275710384) \right)}} = 2.2275710356\end{equation*}
