– Medicine, detecting tumors and laser treatments, advanced scaning procedures.

– Triangulation: makes images detailed and accurate.

• Mountain or land elevation measurements. (altitude, Geography, Mapping ect.) Surveying.

-The study of the properties of triangles and planes….

Interesting….

• Trignometry is often refferd to as a science.• From India the sine function was introduced to

the Arab world in the 8th century, where the term jya was transliterated into jiba or jyb. Early Latin translations of Arabic mathematical treatises mistook jiba for the Arabic word jaib, which can mean the opening of a woman's garment at the neck. Accordingly, jaib was translated into the Latin sinus, which can mean "fold" (in a garment), "bosom," "bay," or even "curve." Hence our word "sine."
