Use Newton's method to find the first 5 approximations of the solution to the equation LaTeX:  \displaystyle e^{- x}= \frac{63 x^{3}}{500} - 6 using LaTeX:  \displaystyle x_0=3 .

Using the formula for Newton's method gives LaTeX:  x_{n+1} =  x_{n} - \frac{- \frac{63 x_{n}^{3}}{500} + 6 + e^{- x_{n}}}{- \frac{189 x_{n}^{2}}{500} - e^{- x_{n}}}   Using LaTeX:  \displaystyle x_0 = 3 and LaTeX:  \displaystyle n = 0,1,2,3, and LaTeX:  \displaystyle 4 gives: LaTeX:  x_{1} =  (3.0000000000) - \frac{- \frac{63 (3.0000000000)^{3}}{500} + 6 + e^{- (3.0000000000)}}{- \frac{189 (3.0000000000)^{2}}{500} - e^{- (3.0000000000)}} = 3.7670771736 LaTeX:  x_{2} =  (3.7670771736) - \frac{- \frac{63 (3.7670771736)^{3}}{500} + 6 + e^{- (3.7670771736)}}{- \frac{189 (3.7670771736)^{2}}{500} - e^{- (3.7670771736)}} = 3.6348020575 LaTeX:  x_{3} =  (3.6348020575) - \frac{- \frac{63 (3.6348020575)^{3}}{500} + 6 + e^{- (3.6348020575)}}{- \frac{189 (3.6348020575)^{2}}{500} - e^{- (3.6348020575)}} = 3.6299396521 LaTeX:  x_{4} =  (3.6299396521) - \frac{- \frac{63 (3.6299396521)^{3}}{500} + 6 + e^{- (3.6299396521)}}{- \frac{189 (3.6299396521)^{2}}{500} - e^{- (3.6299396521)}} = 3.6299332299 LaTeX:  x_{5} =  (3.6299332299) - \frac{- \frac{63 (3.6299332299)^{3}}{500} + 6 + e^{- (3.6299332299)}}{- \frac{189 (3.6299332299)^{2}}{500} - e^{- (3.6299332299)}} = 3.6299332299
