Use Newton's method to find the first 5 approximations of the solution to the equation LaTeX:  \displaystyle e^{- x}= \frac{719 x^{3}}{1000} - 4 using LaTeX:  \displaystyle x_0=1 .

Using the formula for Newton's method gives LaTeX:  x_{n+1} =  x_{n} - \frac{- \frac{719 x_{n}^{3}}{1000} + 4 + e^{- x_{n}}}{- \frac{2157 x_{n}^{2}}{1000} - 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{719 (1.0000000000)^{3}}{1000} + 4 + e^{- (1.0000000000)}}{- \frac{2157 (1.0000000000)^{2}}{1000} - e^{- (1.0000000000)}} = 2.4451697700 LaTeX:  x_{2} =  (2.4451697700) - \frac{- \frac{719 (2.4451697700)^{3}}{1000} + 4 + e^{- (2.4451697700)}}{- \frac{2157 (2.4451697700)^{2}}{1000} - e^{- (2.4451697700)}} = 1.9503283406 LaTeX:  x_{3} =  (1.9503283406) - \frac{- \frac{719 (1.9503283406)^{3}}{1000} + 4 + e^{- (1.9503283406)}}{- \frac{2157 (1.9503283406)^{2}}{1000} - e^{- (1.9503283406)}} = 1.8075508394 LaTeX:  x_{4} =  (1.8075508394) - \frac{- \frac{719 (1.8075508394)^{3}}{1000} + 4 + e^{- (1.8075508394)}}{- \frac{2157 (1.8075508394)^{2}}{1000} - e^{- (1.8075508394)}} = 1.7961600438 LaTeX:  x_{5} =  (1.7961600438) - \frac{- \frac{719 (1.7961600438)^{3}}{1000} + 4 + e^{- (1.7961600438)}}{- \frac{2157 (1.7961600438)^{2}}{1000} - e^{- (1.7961600438)}} = 1.7960906898
