13) We continue to consider as in the previous problem, and denote the class of (a, b) by [(a, b)...
(14) Show that if [(a1,b)- [(a2, b2) and [c,d) (c2, d2)] and bidi(aidi -b)>0 then b2d2(azd2 - b2c2) > 0. (This was the proposition which allows us to know that > on Q is well-defined. )

A complex number is a number of the form a + bi, where a and b are real numbers √ and i is −1. The numbers a and b are known as the real and the imaginary parts, respectively, of the complex number. The operations addition, subtraction, multiplication, and division for complex num- bers are defined as follows: (a+bi)+(c+di) = (a+c)+(b+d)i (a+bi)−(c+di) = (a−c)+(b−d)i (a + bi) ∗ (c + di) = (ac − bd) + (bc + ad)i (a...
Problem 1: Consider a 2nd order homogeneous differential equation of the form aa2y"(x)bay(x) + cy = 0 (1) where a, b, c are constants satisfy so that y(x) = x (a) Find and justify what conditions should a constant m to (1) is a solution (b) Using your solution to (1) Write these three different cases as an equation that a, b,c satisfy. Hint: Use the quadratic formula we should get three different cases for the values that m can...
