C3 Coursework Numerical Methods In this coursework I am going to investigate numerical methods of solving equations. The methods I will use are: 1. Change of sign method‚ for which I am going to use decimal search 2. Fixed point iteration using x = g(x) method 3. Fixed point iteration using Newton-Raphson method I will then compare the methods in terms of speed of convergence and ease of use with hardware/software Contents |Change of sign

Legal Method coursework Part A 1. What were the material facts of the case? The respondent is a married man who had recently been made redundant after 22 years of employment in June 1999. The respondent had a large family in which 8 kids were dependant on him and the other 3 were at university. The respondent occupied 11a Gallagher Road but when his family grew he also purchased 19 Gallagher road in 1992 two houses down from his current residence. The respondent lived on redundancy money

1. Analyze the floating point format IEEE Standard for Binary Floating-Point Arithmetic (IEEE 754) is the most widely-used standard for floating-point computation‚ and is followed by many CPU and FPU implementations. The standard defines formats for representing floating-point numbers and special values together with a set of floating-point operations that operate on these values. It also specifies four rounding modes and five exceptions (Michael L Overton). 2. How floating point numbers are stored
