FIND THE VALUE OF  IN USING TRIGONOMETRI THROUGH MATHEMATICS GAME OF TEN GRADE STUDENTS IN SMA NEGERI 1 AIR JOMAN

Abstract

ABSTRACT

Determining a value of p is very important in mathematics. So, presented to find a value of p in using trigonometri through mathematics game of ten grade students in SMA Negeri 1 Air Joman. Actually, finding a value of p can be done through exterior and interior circle of poligon with trigonometry function. Poligon exterior circle consists of (1) the angles of the regular hexagon on a circle finding a value of p is  3, 141433159 or 3,14. (2) the angles of regular n sides on a circle finding a value of p is  3, 141592654 or 3,14. Poligon interior circle consists of (1) the regular hexagon whose sides tangent the circle finding a value of p is  3, 141911687 or 3,14. (2) the angles of regular n sides on a circle finding a value of p is  3, 141592654 or 3,14. The main problem is that people often say the value of p is irrational. But they can’t show why it is irrational. While in the students case, they don’t know the value of p clearly. So, the writer’s discovery from some references discussing the materials about how to find the value of p through exterior and interior circle of polygon with trigonometry function.
