##### Algebra 2 - Semester 2

Algebra is a branch of mathematics that uses symbols in place of numbers to describe and generalize relationships. In Algebra 2B, you will begin with trigonometry, which is the study of how the sides and angles of a triangle are related. You will examine trigonometric functions and graphs in the context of the unit circle. You will extend your understanding of lines by classifying systems of linear equations. In prior courses, you solved inequalities by graphing. Here, you will solve systems of inequalities, including quadratic and absolute value inequalities that contain restrictions on the variable. You will finish Algebra 2B by applying statistics and probability to make complex decisions. You’ll reach decisions based on representative sampling from a population and by creating and evaluating statistical models.
