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”. (The ancient Egyptians had used some elementary geometry to build the pyramids and remeasure lands flooded by the Nile‚ but neither they nor the ancient Babylonians had developed the concept of

technology generated by a production function f(x) = x2 . The production set is Y = {(y‚ −x) : y ≤ x2 } which is certainly not convex‚ but the input re√ quirement set is V (y) = {x : x ≥ y} which is a convex set. 1.2 It doesn’t change. 1.3 1 = a and 2 = b. 1.4 Let y(t) = f(tx). Then dy = dt so that 1 dy 1 = y dt f(x) 1.5 Substitute txi for i = 1‚ 2 to get f(tx1 ‚ tx2 ) = [(tx1 )ρ + (tx2 )ρ ] ρ = t[xρ + xρ ] ρ = tf(x1 ‚ x2 ). 1 2 This implies that the CES function exhibits constant returns to

1. SUBSTATION EQUIPMENT AND THEIR FUNCTIONS Substations INTRODUCTION: In Power System network‚ in order to transmit and distribute the generated power‚ it is necessary to install “SUBSTATIONS” at strategic points to work at required voltage level since “HIGH VOLTAGE TRANSMISSION” is resorted to. The Sub stations are classified as “GRID” of “RADIAL” Substations. The Grid station is installed in Grid network to reduce the voltage level from 230KV to 110 KV. The radial Station within Distribution net

Form Helps Function Vs. Form Follows Function. Ever since the phrase ‘form follows function’ was coined in 1896 and more so since the creation of the Bauhaus‚ it has been believed by many that the less is more approach is the best way to go about design. That‚ if you make a product to do its sole purpose‚ with no bells and whistles and just the bare bones of design‚ that that is good design. Now I am not saying that this is wrong or that it is a bad thing‚ that style of design has its own merits

The kidney is made up of nephrons‚ which are a kidney’s functional units. These nephrons collect fluid filtered from the blood. The kidney connects to the renal artery‚ renal‚ vein‚ and ureter. Purified blood leaves the kidney using the renal vein‚ urine leaves using a ureter and the renal artery carries blood from the aorta to the kidney. The nephron has a cup-shaped nephric capsule that surrounds a cluster of capillaries called the glomerulus. A good deal of fluid from the blood filters into the

Planning In simple words‚ planning is deciding in advance what is to be done‚ when‚ where‚ how and by whom it is to be done. Planning is the primary function of management. According to Koontz and O’Donnell‚ "Planning bridges the gap from where we are to where we want to go. It makes it possible for things to occur which would not otherwise happen”. The planning process‚ identifies the goals or objectives to be achieved‚ formulates strategies to achieve them‚ arranges or creates the means required

Introduction This assignment focuses on the cost functions of the Dutch Railways. In this tutorial will be an estimated cost function developed for the Nederlandse Spoorwegen (NS). This cost function (expressed in Dutch Guilders) is based on the period of Year 1951 till Year 1993. This due to certain developments that made it more difficult to come to a good approach of a cost function. Based on the cost function‚ developed in this tutorial‚ there will be an answer provided on the question whether
