HOMEWORK 9/15/98

To be handed in by 9/22/98, 12:30 p.m.

Code Newton's method and False Positions. Consider single and double precision versions of these codes. Test your codes out on special cases, and convince me that you have used a sensible stopping criterion. In particular, find all roots of tex2html_wrap_inline253 , tex2html_wrap_inline443 and tex2html_wrap_inline445 and check convergence rates (since you know the exact answers). How should you choose your initial guess(es)? Now find the roots of tex2html_wrap_inline447 . Find the first three positive solutions of the equation x=tan(x). How can you be sure that you have all the right roots? Estimate convergence rates for these last two functions.
