this research to dedicate it for you.this research to dedicate it for you.
Thanks a lot my dear parentsThanks a lot my dear parents....
First, this mathematics research is First, this mathematics research is
about vectors. Vectors have a very about vectors. Vectors have a very
importance in our life, that's why I importance in our life, that's why I
chose a problem from our nature, chose a problem from our nature,
which is calculating the height of Big which is calculating the height of Big
Ben clock.Ben clock.
I started by analyze the givens of the I started by analyze the givens of the
problem, and drawing a simple problem, and drawing a simple
sketch with real measures, and then I sketch with real measures, and then I
chose the best rules and solve itchose the best rules and solve it . .

Finally, I would like to say Finally, I would like to say
that vectors are used in that vectors are used in
types of mathematics and types of mathematics and
can represent anything with can represent anything with
a direction and a magnitude. a direction and a magnitude.
For example, temperature For example, temperature
changes, directions you changes, directions you
move, and a lot of examples move, and a lot of examples
are far more abstractare far more abstract..
