It's an important branch of Mathematics.
TRIGONOMETRY is derived from Greek words[TRI-3, GONON-Angle, METRON-Measure]
HIPPARCHUS [600 BC] first developed a rln b/w da sides & angles of a triangle.
Initially we learn that it's used in right triangles.
But it's used in case of all types of triangles
IT has many applications in the higher figures too
IT has got 6 types of functions
there r many sub-divisions

Trignometry is the study of triangles and mathmatical ways to solve complex problems by setting up triangulation knowing distances and angles. For instance, one can measure the height of a tree without touching the tree and from the ground. This is done by measuring the distance from the trunk to an arbitrary point away from the tree, and then using the angle between the ground and a line of sight to the top of the tree. Problems like these and much more complex problems are possible with Trig.

Originally TRIGONOMETRY was that branch of mathematics concerned with solving triangles using trigonometric ratios which were seen as properties of triangles rather then of angles .
The word Trigonometry comes from the Greek words : Treis = three, Gonia = angle and Metron= measure. The Early Greeks developed the subject by studying the relationship between the arc of the circle - the measure of the central angle - and the chord of the arc.
Initially it was used in Astronomy but later it was much used in Architecture, Navigation, Surveying and Engineering, but in the last two centuries it has been used more for Mathematical Analysis and for repeating Waves and Periodic Phenomena .

Trigonometry (from the Greek trigonon = three angles and metron = measure [1]) is a branch of mathematics which deals with triangles, particularly triangles in a plane where one angle of the triangle is 90 degrees (right triangles). Triangles on a sphere are also studied, in spherical trigonometry. Trigonometry specifically deals with the relationships between the sides and the angles of triangles, that is, the trigonometric functions, and with calculations based on these functions.
This robotic arm on the International Space Station is operated by controlling the angles of its joints. Calculating the final position of the astronaut at the end of the arm requires repeated use of the trigonometric functions of those angles.Trigonometry has important applications in many branches of pure mathematics as well as of applied mathematics and, consequently, much of science.

Trigonometry began as the computational component of geometry. For instance, one statement of plane geometry states that a triangle is determined by a side and two angles. In other words, given one side of a triangle and two angles in the triangle, then the other two sides and the remaining angle are determined. Trigonometry includes the methods for computing those other two sides. The remaining angle is easy to find since the sum of the three angles equals 180 degrees (usually written 180°).

trigo isnt that confusing. you may desire to be attentive to the expressions for sin, cos, tan in a suitable angled triangle, for a commence. you in addition to mght could desire to be attentive to the sin, cos and tan on the universal values of 0,30, 40 5, 60,ninety levels. then some thing on finding the sin's n all at angles better than ninety. there's a hassle-free thank you to bear in mind the sin's of at those values. first make a table wherein the row heading are 0 30 40 5 60 ninety. then i the 1st column, write sin. interior the row coressponding to the sin write the values 0 a million 2 3 4. Divide those numbers by using 4 and then take the sq. root. examine the values under each and every column, coressponding to an attitude as a results of fact the fee of its sin. working example, the sin of 30 levels this sort is a million/2 and of 60 levels is sqrt(3)/2. The values for the cos is opposite of this. so the cos of 60 levels is a million/2 and cos of 30 is sqrt(3)/2. The values for finding tan at an attitude is won by using dividing the sin of that attitude to its cos. so the tan of 60 is sqrt(3) and of 30 is a million/sqrt(3).

Trigonometry, branch of mathematics that deals with the relationships between the sides and angles of triangles and with the properties and applications of the trigonometric functions of angles. The two branches of trigonometry are plane trigonometry, which deals with figures lying wholly in a single plane, and spherical trigonometry, which deals with triangles that are sections of the surface of a sphere.
