Use Newton's method to find the first 5 approximations of the solution to the equation LaTeX:  \displaystyle e^{- x}= \frac{61 x^{3}}{500} - 8 using LaTeX:  \displaystyle x_0=5 .

Using the formula for Newton's method gives LaTeX:  x_{n+1} =  x_{n} - \frac{- \frac{61 x_{n}^{3}}{500} + 8 + e^{- x_{n}}}{- \frac{183 x_{n}^{2}}{500} - e^{- x_{n}}}   Using LaTeX:  \displaystyle x_0 = 5 and LaTeX:  \displaystyle n = 0,1,2,3, and LaTeX:  \displaystyle 4 gives: LaTeX:  x_{1} =  (5.0000000000) - \frac{- \frac{61 (5.0000000000)^{3}}{500} + 8 + e^{- (5.0000000000)}}{- \frac{183 (5.0000000000)^{2}}{500} - e^{- (5.0000000000)}} = 4.2089691662 LaTeX:  x_{2} =  (4.2089691662) - \frac{- \frac{61 (4.2089691662)^{3}}{500} + 8 + e^{- (4.2089691662)}}{- \frac{183 (4.2089691662)^{2}}{500} - e^{- (4.2089691662)}} = 4.0424890745 LaTeX:  x_{3} =  (4.0424890745) - \frac{- \frac{61 (4.0424890745)^{3}}{500} + 8 + e^{- (4.0424890745)}}{- \frac{183 (4.0424890745)^{2}}{500} - e^{- (4.0424890745)}} = 4.0355016964 LaTeX:  x_{4} =  (4.0355016964) - \frac{- \frac{61 (4.0355016964)^{3}}{500} + 8 + e^{- (4.0355016964)}}{- \frac{183 (4.0355016964)^{2}}{500} - e^{- (4.0355016964)}} = 4.0354896916 LaTeX:  x_{5} =  (4.0354896916) - \frac{- \frac{61 (4.0354896916)^{3}}{500} + 8 + e^{- (4.0354896916)}}{- \frac{183 (4.0354896916)^{2}}{500} - e^{- (4.0354896916)}} = 4.0354896915
