A set of computer-oriented, supplemental activities is offered which can be used with a course in advanced algebra and trigonometry. The activities involve use of the BASIC programming language; it is assumed that the teacher is familiar with programming in BASIC. Students will learn some BASIC; however, the intent is not to develop proficient programmers. The idea is to allow students to observe results and to solve problems which usually are not accomplished because of time and difficulty. Nine units present student objectives and activities for the following topics: (1) getting acquainted with the computer (logging on and off, storing programs, learning the keyboard); (2) introduction to BASIC (writing programs); (3) functions and relations (linear functions); (4) systems of equations and inequalities; (5) polynomials; (6) sequences and series; (7) real numbers; (8) exponents and logs; and (9) trigonometry.
