Solutions to Problem Sets 1 Three Questions at the End of the Preface Gilbert Strang, Introduction to Linear Algebra, 6th Edition (2023) 1. When can lines of lengths r,s,t form a triangle? They must satisfy the strict triangle inequalities r < s+t s < r +t t < r +s If we allow equality, the triangle will have angles of 0,0 and 180 degrees.

Multiplying the right side (1, 11) by 4 will multiply the solution by 4 to give the new solution (x, y) = (8, −4). 3 Subtract −1 (or add 1 2) times equation 1.

1.1 Algebra The word \algebra" means many things. The word dates back about 1200 years ago to part of the title of al-Khwarizm 's book on the subject, but the subject itself goes back 4000 years ago to ancient Babylonia and Egypt. It was about solving numerical problems that we would now identify as linear and quadratic equations. Versions of the quadratic formula were used to nd solutions to ...

8 If k = 3 elimination must fail: no solution. If k = −3, elimination gives 0 = 0 in equation 2: infinitely many solutions. If k = 0 a row exchange is needed: one solution. 9 On the left side, 6x − 4y is 2 times (3x − 2y). Therefore we need b2 = 2b1 on the right side. Then there will be infinitely many solutions (two parallel lines become ...

0 0 0 we find a special solution that corresponds to each free vector by assigning ones to each free variable in turn and then solving for the pivot variables.

The linear system has infinitely many solutions given by the one parameter set S = 2x + 2y = 2 {(1 − t, t) t Notice that the second equation is twice the first and the equations represent the same line. | ∈ R}.

Solution for Problem 5.10: We could just keep guessing possibilities until we find the answer, but a little algebra finds the answer quickly. We convert the words to math by first defining two variables, one for each team:

A thorough introduction for students in grades 6-9 to algebra topics such as linear equations, ratios, quadratic equations, special factorizations, complex numbers, graphing linear and quadratic equations, linear and quadratic inequalities, functions, polynomials, exponents and logarithms, absolute value, sequences and series, and more!
