Introduction to Trigonometry. Measurement of triangles is known as Trigonometry. Here we shall be dealing with the relation of sides and angles of a right-angled triangle. In the above diagram Base = AB, Perpendicular = BC, Hypotenuse = AC and angle of reference = ∠A.
Trigonometry: Law of Sines, Law of Cosines, and Area of Triangles. Formulas, notes, examples, and practice test (with solutions) Topics include finding angles and sides, the “ambiguous case” of law of Sines, vectors, navigation, and more.
In this figure, the line AC drawn from the eye of the student to the top of the minar is called the line of sight. The student is looking at the top of the minar. The angle BAC, so formed by the line of sight with the horizontal, is called the angle of elevation of the top of the minar from the eye of the student.

The two different types of trigonometry are: Plane Trigonometry. Spherical Trigonometry. In this article, let us discuss the six important trigonometric functions, ratios, trigonometry table, formulas and identities which helps to find the missing angles or sides of a right triangle.
trigonometric ratios in solving the problems related to heights and distances. In this Chapter, we will generalise the concept of trigonometric ratios to trigonometric functions and study their properties. 3.2 Angles Angle is a measure of rotation of a given ray about its initial point. The original ray is Chapter 3 TRIGONOMETRIC FUNCTIONS Arya ...
