The document describes using the Newton-Raphson method to solve two equations: 1) f(x) = e−x/4(2 − x) − 1 with an initial value of 0. The method converges to a solution of 0.7836 after 4 iterations, with an error of 0. 2) f(x) = x/sinx with an initial value of π-2 and tolerance of 10-4. Graphing the function shows no visible roots, and iterating with the Newton-Raphson method results in an erroneous value of -35550.2623.
