Project 3. (Due 8/8)
1. Rewrite the previous Newton program with all the previous Math and I/O features but now with Newton and Taylor as two classes.
2. The functions cos(x) and sin(x) and the nonlinear function should be defined outside of these classes and accessed by the objects instantiated by these classes via call by reference.
3. All arrays should be allocated in dynamic memory.
4. Use prototype declaration for both functions and classes, i.e., move all definitions below the main() function.
5. You should submit I/O files as well.
6. In your email to me, write project # and your Chinese name on the 主旨: line.

Project 2. (Due 8/1) Rewrite the previous Newton program with the nonlinear function cos(x) − x³to include the following new features:
Part A. C++: 1. Functions (with declaration, call, definition). 2. Use I/O files instead of cin and cout.
3. Array or pointer.
Part B. Math: 1. Show by an output table that Newton’s method coverges quadratically. 2. Use Taylor series to approximate the functions cos(x) and sin(x) in your program. Read the article about Gottfried Leibniz and Brook Taylor on Wikepedia.

Project 1. (Due 7/25) Write a C++ program for finding a root of a nonlinear function f(x) by using Newton’s method. Read the article about Issac Newton on Wikepedia. Send your program to my email address: jinnliu@nuk.edu.tw.
