## Task #1

Write a program to use **fixed point iteration** to solve the equation f(x)=e^(-x) – x where inputs will be the initial guess, and maximum error (es). If the approximation error (ea) is less than es your program should stop continuing any iterations.

## Task #2

Write a program to use **Newton Raphson Method** to solve the equation f(x)=e^(-x) – x where inputs will be the initial guess, and maximum error (es). If the approximation error (ea) is less than es your program should stop continuing any iterations.

## Task #3

Write a program to use ** Secant Method** to solve the equation f(x)=e^(-x) – x where inputs will be the initial guess, and maximum error (es). If the approximation error (ea) is less than es your program should stop continuing any iterations.
