SUMMARY
This discussion centers on solving nonlinear equations using Newton's Method in MATLAB. The user presents three equations with initial values and compares their manually calculated roots to those obtained from MATLAB. The discrepancies noted are: for cos(x) = (e^x) - 1, the user calculated 0.6931 while MATLAB returned 0.6013; for ln(x) = x^2 - 1, both the user and MATLAB agreed on 1; and for x^2 = 2x + 2, the user found 2.7321, but MATLAB reported an error. The user seeks clarification on whether using Newton's Method affects the results.
