Calculus B - Lab 5 

TA: Patrick C. Rowe 

This lab will be devoted to writing a procedure which carries out Newton's Method. 

Use the previous Lab, plus the commands you know to construct a procedure. 

Your procedure should take the following parameters: 

• an expression in 'x'

• an initial guess of a zero

• acceptable error

There are two ways to calculate the error. The current iteration can be compared with the previous iteration, or the expression value can be calculated at the current iteration. Both ways can result in correct and incorrect results. 

Your procedure should return the following: 

• final approximation to a zero

• the number of iterations required

Assignment: Write a report concerning the procedure you wrote to implement Newton's Method. Include the procedure, a graph, and commentary about how the calculations are carried out. 

Due Tuesday, February 27th.
