Trigonometry is the oldest branch of mathematics. This concept was first used by Aryabhata in Aryabhatiyam in A. Trigonometry is a word consisting of three Greek words: Tri-Gon-Metron. So, trigonometry is the study related to the measure of sides and angles of a triangle in particular, right triangles in CBSE class Trigonometry is used in astronomy to determine the position and the path of celestial objects.
Astronomers use it to find the distance of the stars and planets from the Earth. Captain of a ship uses it to find the direction and the distance of islands and light houses from the sea. Surveyors use to map the new lands. Objective of Class 10 Trigonometry: Identifying the opposite side, adjacent side and hypotenuse of right triangle with respect to Ch 8 Class 10 Maths Introduction To Pdf given angle A.
Defining the six rations sine, cosine, tangent, secant. Finding the values of trigonometric rations of a given Class 10 Maths Ch 12 All Formulas With right angled triangle. Finding the values of trigonometry rations of some standard angles 0, 30, 45, 60 and 90 in degrees.
Using complementary angles and applying it into trigonometric identities to prove another identities. Long ago, ancient Greek and Indian astronomers used these handy techniques to measure the distances of stars and planets from the Earth very precisely. Even today, most of the technologically advanced methods used in Engineering and Physical Sciences are based on trigonometrical concepts. This branch of Mathematics, called Trigonometry is extremely helpful in dealing with height and distances which are not easy to measure.
In this chapter, you will first study the ratios of sides of a right triangle concerning its acute angles and see how these ratios only depend on the measure of the angles involved. You will then go through the names and definitions of these six trigonometric ratios of an angle.
At last, you will also establish some relationships among these trigonometric ratios which are termed as trigonometric identities.
Apart from the theoretical and application part, this chapter is very important and will always serve as fundamentals and pre-requisites for nearly all streams of higher studies including reputed national and international competitions.
From the exam point of view, this chapter remains one of the interesting and scoring one with a good number of questions being asked frequently in board exams every year. Taking mock tests on the chapter will give you a better understanding of trigonometric concepts and where you stand in terms of your preparation.
