What is a system of linear equation? What is the condition for a unique
solution? Name three methods for solving system of equations. Give three
points of comparison between direct methods and iterative methods for solving
system of linear equations

Mention the use of the following numerical methods/parameters (i) Aitken’s
methods (ii) Correlation coefficient (iii) finite difference method (iv) least
square method and (v) Gauss-Jordan method.

What is correlation? How is it different from regression?

Name any one measure of correlation. Write down its equation.

Write a C++ program to declare and initialize the pairs of values x and y given
by (0,-12), (1,0), (2,0), (3,6) and (4,12). In the same program include statements
to interpolate the value of y for x=3.2 using a fourth degree polynomial.

Write a C++ program to declare and initialize 10 pairs of values. Add more

statements in this program to compute the coefficient of correlation.
