Use Newton's method to find the first 5 approximations of the solution to the equation LaTeX:  \displaystyle e^{- x}= \frac{141 x^{3}}{200} - 4 using LaTeX:  \displaystyle x_0=1 .

Using the formula for Newton's method gives LaTeX:  x_{n+1} =  x_{n} - \frac{- \frac{141 x_{n}^{3}}{200} + 4 + e^{- x_{n}}}{- \frac{423 x_{n}^{2}}{200} - e^{- x_{n}}}   Using LaTeX:  \displaystyle x_0 = 1 and LaTeX:  \displaystyle n = 0,1,2,3, and LaTeX:  \displaystyle 4 gives: LaTeX:  x_{1} =  (1.0000000000) - \frac{- \frac{141 (1.0000000000)^{3}}{200} + 4 + e^{- (1.0000000000)}}{- \frac{423 (1.0000000000)^{2}}{200} - e^{- (1.0000000000)}} = 2.4752546501 LaTeX:  x_{2} =  (2.4752546501) - \frac{- \frac{141 (2.4752546501)^{3}}{200} + 4 + e^{- (2.4752546501)}}{- \frac{423 (2.4752546501)^{2}}{200} - e^{- (2.4752546501)}} = 1.9686335609 LaTeX:  x_{3} =  (1.9686335609) - \frac{- \frac{141 (1.9686335609)^{3}}{200} + 4 + e^{- (1.9686335609)}}{- \frac{423 (1.9686335609)^{2}}{200} - e^{- (1.9686335609)}} = 1.8199918172 LaTeX:  x_{4} =  (1.8199918172) - \frac{- \frac{141 (1.8199918172)^{3}}{200} + 4 + e^{- (1.8199918172)}}{- \frac{423 (1.8199918172)^{2}}{200} - e^{- (1.8199918172)}} = 1.8077066827 LaTeX:  x_{5} =  (1.8077066827) - \frac{- \frac{141 (1.8077066827)^{3}}{200} + 4 + e^{- (1.8077066827)}}{- \frac{423 (1.8077066827)^{2}}{200} - e^{- (1.8077066827)}} = 1.8076264944
