Pembelajaran Matematika Berbantuan Kalkulator: Studi Kasus Penggunaan Kalkulator Texas Instrument TI 89 pada PBM Matematika di SMK MUHAMMADIYAH IV YOGYAKARTA

In learning mathematics, we can use a tool to count. Usually we use the auxiliary arithmetic alata commonly known by the term calculator. The calculator has two kinds / types, namely ordinary calculator and scientific calculator. Regular calculator that has often we find and use. Scientific calculator is one example of the graphing calculator. Graphing calculator can memecahakan denagn math problems quickly and displays the results in graphical form. In addition to the graphing calculator can also create a program used to solve mathematical problems.

There are several important orders from Texas Instruments calculator TI 89, namely Solve command is command feature algebra. We can determine the set of settlement on Linear Inequalities, Quadratic Equations, Equations 2 System of linear equations, systems of linear equations with each other quadratic equations, Systems of Equations 3 variables.  Simult command is command of the feature matrix. We can solve systems of linear equations three variables by using this command. Ekspand command is command feature algebra. Examples of problems that can be resolved is the problem of determining the roots of quadratic equations are known. In addition, we can develop new quadratic equations, systems of linear equations with one another quadratic equation, the question of stories related to inequality, etc.

This graphing calculator can be used as a means of learning mathematics in the classroom, and students can be involved directly in the calculation process amtematika, so students are also actively involved in perhitunagan not only get results only. Students are also able to match the results of the answer without using a regular calculator. Graphing calculators can speed up the meaning, reflect, analyze data and connect it. One example of Texas Instruments graphing calculator is the TI 89.

Many of the ease with which we can get with use graphing calculator. With a graphing calculator we can make, graph quadratic equations, graph linear equations system, and also graph linear inequalities, graph linear inequalities, etc.
