Question 1: What are the trigonometric functions?
Answer: Usually, trigonometric calculations are done using the trigonometry ratios. There are a total six trigonometric ratios out of which two (Cos and Sin) are basic ratios. The main ratios are Sin, Cos and Tan such that Tan is derived from sin and Cos. Cosec, Sec and Cot are the inverse of the three main ratios. Cosec is the inverse of Sin, Sec is the inverse of Cos and Cot is the inverse of Tan. These ratios are also called trigonometric functions.
Question 2: Why only right-angled triangles are used in trigonometry?
Answer: Trigonometry is used to define the relations between angles and sides of a triangle. The triangles are not specifically right-angled triangles but any triangle. The reason why we use right angle triangles to derive formulas is because the sides and angles of a right-angled triangle have fixed relationships which is shown in Pythagoras theorem. According to Pythagoras theorem, the square of the hypotenuse of a right-angled triangle is equal to the sum of the square of its base and length. The other reason for using right angled triangles is the fact that every triangle can be bisected into two or more right-angled triangles. Thus, the value of any triangles can be found if the values of the right angled triangle is given.
Question 3: What is the application of Trigonometry in real life?
Answer: Trigonometry finds its applications in various fields. We use Trigonometry to find the angle of elevation, the height of an object at a particular distance or the distance from an object of a given height. Trigonometry is used by architecture to find the inclination of a roof, the height of a building, etc. It is used by detectives to find out the height of the criminal by knowing at which angle the bullet was shot and the distance from where it was shot. Marine biologists and marine engineers also use Trigonometry for various purposes, for example to understand the size and behaviour of sea animals, to find out the minimum distance to be maintained from huge icebergs, etc. Vedantu makes Trigonometry more interesting for you by simplifying the complicated numerical and relating each of them to real-life scenarios.
