Submitted By: Ma. Karla Rachelle Ulibas Student Submitted To: Mr. Ray-ann Buenafe Instructor HISTORY OF TRIGONOMETRIC FUNCTIONS Trigonometric functions seem to have had their origins with the Greek’s investigation of the indirect measurement of distances and angles in the “celestial sphere”.

Once the formulas were obtained‚ the experiment was started by finding the boiling point of the unknown liquid “D” and the melting point of the unknown solid “C”. Results were used to identify the identities of the unknowns. After this‚ a Fourier Transform Infrared (FTIR) was used to obtain a spectrum of the unknowns. This spectrum was then used to find the structure of each unknown. The melting point of a substance served as a reference point in determining the unknown solid. It is defined

Abstract The Home Automation Profile supports a various of devices for the home along with lighting‚ heating and cooling‚ and widely accepted for multiple needs. It is the automatic or semi-automatic control and monitoring of household appliances and residential house features like doors‚ gate and even the windows. Hence the Home Automation profile allow a greater range of control and integration of different devices in the home by automatic. These systems use PC‚ mobile internet

earth ’s atmosphere that is theorized to contribute to climatic change and rising sea levels due to heat trapped by greenhouse gases. Jean Baptiste Joseph Fourier was a French mathematician who came up with the first theory of global warming in 1824 when he discovered that the Earth’s temperature was increasing (NewspaperArchive.com par 3). Fourier argued that “the Earth’s atmosphere traps solar radiation and reflects it back toward the earth” (NewspaperArchive.com par 3). It was later named the greenhouse
