Homework #2 Notes

Problem 1:

	I'm not sure why my simplify results for trig_expr differ from those
	of the example, since we both use the same side relation.  The example
	result is achieved with the conversion of cos(x)^2 = 1 - sin(x)^2.
 
Problem 2:

	Here are some postscript plots of the various functions used:

	(1.1)  function 
	       first-order 
	       second-order 
	       third-order 
	(1.2)  function 
               indefinite integral 
	(1.3)  function 
	(1.4)  function (with 3rd,6th,9th order) 

Problem 3:

	 Text output  from the Maple worksheet rev_test.ms
	to test the prodecdure reverse.

Problem 4:

	 Text output  from the Maple worksheet pla_test
	to test the prodecdure planck.


Problem 5:

	 Text file  from the README results for newt3.
