Trigonometry is the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles. Throughout history, trigonometry has been applied in areas such as geodesy, surveying, celestial mechanics, and navigation. The concept of Trigonometry is given by a Greek mathematician Hipparchus. Trigonometry is all about a right-angled triangle. It is one of those divisions in mathematics that helps in finding the angles and missing sides of a triangle by the help of trigonometric ratios.
The angles are either measured in radians or degrees. The six important trigonometric functions trigonometric ratios are calculated by the below formulas using above figure.
It is necessary to get knowledge regarding the sides of the right angle triangle, because it defines the set of important trigonometric functions. The values of trigonometrical ratios of standard angles are very important to solve the trigonometrical problems. Therefore, it is necessary to remember the value of the trigonometrical ratios of these standard angles. The sine, cosine and tangent of the standard angles are given below in the table.
The Trigonometric formulas or Identities are the equations which are true in the case of Right-Angled Triangles. Some of the special trigonometric identities are as given below —. For angles A and B, we have the following relationships:. Question 6 : Find the value of x.
Practice these questions given here to get a deep knowledge of Trigonometry. Use the formulas and table given in this article wherever necessary. Determine the values of sin P, cos P and tan P. Sometimes, we have to find the height of a tower, building, tree, distance of a ship, width of a river, etc. Though we cannot measure them easily, we can determine these by using trigonometric ratios.
The line of sight or the line of vision is a straight line to the object we are viewing. If the object is above the horizontal from the eye, we have to lift up our head to view the object.
In this process, our eye move, through an angle. This angle is called the angle of elevation of the object. If the object is below the horizontal from the eye, then we have no turn our head downwards no view the object. In this process, our eye move through an angle.
This angle is called the angle of depression of the object. Example: A 25 m long ladder is placed against a vertical wall of a building. The foot of the ladder is 7m from base of the building.Explore the surplus collection of trigonometry worksheets that cover key skills in quadrants and angles, measuring angles in degrees and radians, conversion between degrees, minutes and radians, understanding the six trigonometric ratios, unit circles, frequently used trigonometric identities, evaluating, proving and verifying trigonometric expressions and the list go on Grasp and retain trigonometric concepts with ease employing these visually appealing charts for quadrants and angles, right triangle trigonometric ratio chart, trigonometric ratio tables, allied angles and unit circle charts to mention a few.

A student should note that triangles are made out of right angles. From this, basic trigonometric ratios are found.
There are six basic trigonometric ratios that are evaluated from the sides of a right-angled triangle. Based on the value of the ratio of the sides in a right-angled triangle, trigonometric ratios are defined as the values of all the trigonometric functions. It can be said that the ratios of the sides with respect to any of its acute angles, represent the trigonometric ratio of that specific angle.
Referring to the above figure, it may be seen it is a right-angled triangle, and at B, it is right angled. Trigonometric ratios are evaluated from the sides of the above right-angled triangle, and are six in numbers. The ratios are listed as sine, cosine, tangent, cotangent, cosecant, and secant. The trigonometric ratios with respect to angle C are defined below:. Sine of an angle is represented as the ratio of the perpendicular side AB to the angle hypotenuse AC. Cosine of an angle is represented as the ratio of the side adjacent to side BC, to that angle to the hypotenuse AC.
Tangent of an angle is represented as ratio of the perpendicular side AB, to that angle, of the side adjacent to that angle. Cosecant of an angle is defined as the multiplicative inverse of sine. Cotangent of an angle is represented as multiplicative inverse of the tangent. Secant of an angle is represented as a multiplicative inverse of cosine.
