1 Introduction
and the importance The tree is the environment in which we can see, according to the General, which is something that is important to many humans, both air and shade. In addition to that, we will be able to see the trees, according to different places, such as forests. Building construction, then maybe the trees also appear in the problems of teaching and learning in mathematics as well, such as "one tree using wire ties at the top away from 2 feet, and then retrieved from the main binding cone trees 15 feet. 25 feet high, this tree a few feet, "which is related to p. Tana or korat is about finding the height of a tree by using the trigonometric ratios matter. 38 meters if the angle with which the cone tree size is 16 degrees and a perk that the amount of tree size is 13 degrees shall find out the height of the trees ", etc.
. To make organized thinking, we are able to measure the height of the tree is really using the trigonometric ratio's knowledge, or could not have made this project more
purpose 1.To find the height of a tree or building construction such as Sao. School building to 2
thought process skills training a mathematical calculation of
3. in order to be able to calculate the ratio of the simple hypothesis trikon
.Be able to use the knowledge of trigonometry to calculate the approximated height of the tree has the benefits of project work
1. find the height of things that cannot be measured by devices such as cartridge m
2.Can think of a mathematical process analysis has
3. can calculate the ratio trikon easily
4. can be used as a medium of teaching and learning.
