Recommended: Trigonometry in our daily life

Introduction to prepare for uses of trigonometric functions: The general trigonometric functions are sin, cos, tan functions only. The students uses trigonometric functions in problems to find the distance, length of the shadow, poles, height of the building, angles between the slopes, etc. The trigonometric functions are kept in the student’s curriculum in order to prepare them for a well defined practical application or experience of the problems that are used in applying in there day to day life. Now, let us see some solved examples to prepare for uses of trigonometric functions, Examples in prepare for uses of trigonometric functions: Example 1: A communication tower in the planet Venus has a height of 315m which is used to communicate with earth. It casts a shadow of length 82m in evening. So, find the angle of elevation with respect to the sun and the tower? Solution: Given data: Height of the tower is- 315m, Length of the shadow is – 82m. moon So, the an...

    Study of Geometry gives students the tools to logical reasoning and deductive thinking to solve abstract equations. Geometry is an important mathematical concept to grasp as we use it in our life every day. Geometry is the study of shape- and there are shapes all around us. Examples of geometry in everyday life are- in sport, nature, games and architecture. The game Jenga involves geometry as it is important to keep the stack of tiles at a 90 degrees angle, otherwise the stack of tiles will fall over. Architects use geometry everyday- it is essential when designing buildings- shape, angles and area and perimeter are some of the geometry concepts architects

  • Trigonometry: What Is Trigonometry?

    Trigonometric ratios are something you would hope to never use, but this term I was forced to find the height of a given eucalyptus tree. No instructions were given for this task other than the fact that I was not allowed physically measure the tree itself. The tools I was given were a large protractor and a measuring tape. I immediately sat down and thought why we were given the specific tools. I soon came up with a theory knowing that If I can find an angle that lines up with the top of the tree (θ) and the adjacent side (length

  • Abstract Geometry

    An example of the difference in the abstract geometry and the measurement geometry is the sum of the measures of the angles of a trigon. The sum of the measures of the angles of a trigon is 180 degrees in Euclidian geometry, less than 180 in hyperbolic, and more than 180 in elliptic geometry. The area of a trigon in hyperbolic geometry is proportional to the excess of its angle sum over 180 degrees. In Euclidean geometry all trigons have an angle sum of 180 without respect to its area. Which means similar trigons with different areas can exist in Euclidean geometry. It is not possible in hyperbolic or elliptic geometry. In two-dimensional geometries, lines that are perpendicular to the same given line are parallel in abstract geometry, are neither parallel nor intersecting in hyperbolic geometry, and intersect at the pole of the given line in elliptic geometry. The appearance of the lines as straight or curved depends on the postulates for the space.

  • Antigone And Tris Compare And Contrast

    335 Words  | 1 Pages

    I learned a lot of new information during this project. I learned that there are many protagonists that compare to the ones in the books we read. I chose to present on Antigone and Tris. Tris is the main character in a book series called Divergent. There are three books in this novel set. Antigone and Tris can be compared in many ways. Both of their societies are afraid of disobeying. This is shown throughout both novels that I presented on. Antigone’s society was afraid of Creon. They wanted to follow the God’s laws but Creon was threatening to kill them if they disobeyed. Tris’s society was afraid of divergent people, which was what Tris was. There are many other comparisons between the two characters. Another is that both of their families

  • Calculus and Its Use in Everyday Life

    1302 Words  | 3 Pages

    Ever wonder how scientists figure out how long it takes for the radiation from a nuclear weapon to decay? This dilemma can be solved by calculus, which helps determine the rate of decay of the radioactive material. Calculus can aid people in many everyday situations, such as deciding how much fencing is needed to encompass a designated area. Finding how gravity affects certain objects is how calculus aids people who study Physics. Mechanics find calculus useful to determine rates of flow of fluids in a car. Numerous developments in mathematics by Ancient Greeks to Europeans led to the discovery of integral calculus, which is still expanding. The first mathematicians came from Egypt, where they discovered the rule for the volume of a pyramid and approximation of the area of a circle. Later, Greeks made tremendous discoveries. Archimedes extended the method of inscribed and circumscribed figures by means of heuristic, which are rules that are specific to a given problem and can therefore help guide the search. These arguments involved parallel slices of figures and the laws of the lever, the idea of a surface as made up of lines. Finding areas and volumes of figures by using conic section (a circle, point, hyperbola, etc.) and weighing infinitely thin slices of figures, an idea used in integral calculus today was also a discovery of Archimedes. One of Archimedes's major crucial discoveries for integral calculus was a limit that allows the "slices" of a figure to be infinitely thin. Another Greek, Euclid, developed ideas supporting the theory of calculus, but the logic basis was not sustained since infinity and continuity weren't established yet (Boyer 47). His one mistake in finding a definite integral was that it is not found by the sums of an infinite number of points, lines, or surfaces but by the limit of an infinite sequence (Boyer 47). These early discoveries aided Newton and Leibniz in the development of calculus. In the 17th century, people from all over Europe made numerous mathematics discoveries in the integral calculus field. Johannes Kepler "anticipat(ed) results found… in the integral calculus" (Boyer 109) with his summations. For instance, in his Astronomia nova, he formed a summation similar to integral calculus dealing with sine and cosine. F. B. Cavalieri expanded on Johannes Kepler's work on measuring volumes. Also, he "investigate[d] areas under the curve" ("Calculus (mathematics)") with what he called "indivisible magnitudes.
