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”. (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

Boolean Functions - Computer Organization (IT 25) BOOLEAN FUNCTIONS A Boolean function consists of a binary variable denoting the function‚ an equals sign and an algebraic expressions formed by using binary variables the constants 0 and 1‚ the logic operation symbols‚ and parentheses. For a given value of the binary variables‚ Boolean function can be equal to either 1 or 0. Example: F = X + Y’Z The two parts of the expression X and Y’Z‚ are called terms of the function F. The function F is

3.3 Derivatives of Trigonometric Functions Math 1271‚ TA: Amy DeCelles 1. Overview You need to memorize the derivatives of all the trigonometric functions. If you don’t get them straight before we learn integration‚ it will be much harder to remember them correctly. (sin x) = cos x (cos x) = − sin x (tan x) = sec2 x (sec x) = sec x tan x (csc x) = − csc x cot x (cot x) = − csc2 x A couple of useful limits also appear in this section: lim

Properties of Trigonometric Functions The properties of the 6 trigonometric functions: sin (x)‚ cos (x)‚ tan(x)‚ cot (x)‚ sec (x) and csc (x)are discussed. These include the graph‚ domain‚ range‚ asymptotes (if any)‚ symmetry‚ x and y intercepts and maximum and minimum points. Sine Function: f(x) = sin (x) * Graph * Domain: all real numbers * Range: [-1 ‚ 1] * Period = 2pi * x-intercepts: x = k pi ‚ where k is an integer. * y-intercepts: y = 0 * Maximum points: (pi/2

sports event estimates that if the event is announced x days in advance‚ the revenue obtained will be R(x) thousand $ where R(x) = 400 + 120x - x2. The cost of advertising event for x days is C(x) thousand $‚ where C(x) = 2x2+300. a) Find profit function P(x) =R(x) – C(x) & sketch graph. b) How many days in advance should the event be announced in order to maximize profit. What is the max profit? c) What is the ratio revenue to cost Q(x) =R(x)C(x) at the optimal announcement time found

Sine‚ Cosine‚ and Tangent Functions Essential Questions: What is a function? How is the sine definition different from the sine function? Cosine? Tangent? From the graph of these functions‚ list some properties that describe them? Rebecca Adcock‚ a former student of EMAT 6690 at The University of Georgia‚ and I agree that the concept of the Sine‚ Cosine Functions will occur at lesson 6 of a beginning trigonometry unit.
