There are 18 questions in full, however, only FOUR questions are for your coursework, which will be chosen (determined) by the computer (by the method of a random choice).There is no mark if you do the questions selected by yourself.
1. (a) Avoiding large errors, overflflow and underflflow. For 100 values of x over the interval [10
14
, 10
16
], evaluate the following expression
y =
p
2x
2
+ 1 1 1
and then develop a new expression which is mathematically equivalent, plot them, and based on the graphs, tell which is better in terms of resisting the loss of signifificance.
