Program the Gaussian elimination method with no partial pivoting for solving a linear system of the
form Ax=b, where b is a single column vector. Your function should take in a coefficient matrix A,
and a single input vector b. Your function should return the solution vector x.
Your code should also return the appropriate error message.
The first line of your function should look like:
function x = gaussElimination (A,b)

- • Suppose that we want to find a solution of the equation sin² (2) + 1-2x = 0, on the interval [0, π/2]. Is there a solution of the equation in this interval? How do you know?arrow_forwardFor a quadratic equation ax-+ bx + c = 0 (a#0), discriminant (b--4ac) decides the nature of roots. If it's less than zero, the roots are imaginary, or if it's greater than zero, roots are real. If it's zero, the roots are equal. For a quadratic equation sum of its roots = -b/a and product of its roots = c/a. Write a complete C program that calculates the roots of a quadratic equation. The program must request inputs of a,b, and c from the user and print the entered equation, and its roots into the output stream.arrow_forward1.
