Trigonometry Is Essential To Physics. Here Are The Basics
Trigonometry is the branch of mathematics that deals with the sides and angles of triangles. The most common tasks in trigonometry involve calculating certain trigonometric ratios, namely the sine, cosine, and tangent of an angle in a triangle. By using a trigonometric table or the SOHCAHTOA method, you can easily find the basic trigonometric numbers of the most common angles.

To remember the trigonometric table, use the abbreviation “SOHCAHTOA”, which stands for “sine opposite hypotenuse, cosine adjacent hypotenuse, adjacent tangent opposite. For example, if you want to calculate the sine of an angle or triangle, you know that sine. Based on “SOHCAHTOA”” Sine Opposite Hypotenuse”. So, you simply divide the hypotenuse opposite the triangle by the hypotenuse to get the sine.

English: This is a table of exact values of cosine and angles that are multiples of 3°. Of course, this table can be continued by using the properties of complementary angles and adding tangent values by calculating the ratio of sine and cosine. Values are expressed as (5 +/- sqrt(5)), (2 +/- sqrt(3)) and square roots of numbers 2, 3, 5, 6.

A trigonometric table helps to find the values of trigonometric ratios for standard angles like 0°, 30°, 45°, 60° and 90°. A trigonometric table includes trigonometric ratios – sine, cosine, tangent, cosecant, secant, cotangent. These ratios, for short, are written as sin, cos, tan, cosec, sec, and cot. Solving trigonometric problems requires values of trigonometric ratios of standard angles in a trigonometric table.
Trigonometry deals with the measurement of angles and problems related to angles. The word trigonometry is derived from the Latin word trigonometry. Trigonometry uses the relationship between the angles and sides of a triangle.
Double Angle Formula (sine, Cosine, And Tangent)
A trigonometric table is a collection of trigonometric ratio values for various standard angles, including other angles such as 0°, 30°, 45°, 60°, 90°, sometimes 180°, 270°, and 360°. A table format. Because of the patterns in trigonometric ratios and even between angles, it is easy both to estimate values from a trigonometric table and to use the table as a reference to calculate trigonometric values for various other angles. Trigonometric functions are sine function, cosine function, tan function, cot function, sec function and cosec function.
Trigonometry refers to the relationship between the sides of a triangle (a right triangle) and its angles. A trigonometric value is a collective term for the values of different ratios such as sine, cosine, tangent, secant, cotangent and cosecant in the trigonometric table. All trigonometric ratios are related to the sides of a right triangle and their values are found using the following ratios.
The values of trigonometric ratios for angles 0°, 30°, 45°, 60°, and 90° in the trigonometric table are often used to solve trigonometric problems. These values are connected to the measurement of lengths and angles of a right triangle. So 0°, 30°, 45°, 60° and 90° are called standard angles in trigonometry.
A trigonometric table is a collection of trigonometric function values for various standard angles, including 0°, 30°, 45°, 60°, 90°, as well as other angles such as 180°, 270° and 360°, in tabular format. The values of trigonometric ratios are easy to estimate in a trigonometric table and the table is easy to use as a reference to calculate trigonometric values for various other angles because of the patterns in trigonometric ratios and even between angles.

The table includes trigonometric ratios – sine, cosine, tangent, cosecant, secant and cotangent. In short, these ratios are written as sin, cos, tan, cosec, sec, and cot. It is best to remember the values of the trigonometric ratios of these standard angles.
Using the table above, find the values of sin π/6, cos π/6, tan π/6, sin π/4, cos π/4, tan π/4, sin π/3, cos π/3, tan π/3 in radians. , sin π/2, cos π/2, and tan π/2 are easily found. Trigonometric table has wide application in fields like science and engineering.
The trigonometric table may seem complicated at first, but is easily learned through the sine values for the 8 standard angles. Before making the table, there are some principles to be followed as given below,
Sin (180° – x) = sin x sin (180° + x) = -sin x sin (360° – x) = -sin x

The following trigonometric table covers the value of trigonometric ratios for all base angles from 0º to 360º.
Let’s learn a handy trick to remember the trigonometric table easily! Assign standard angles to each finger as shown in the figure. To fill in the sine values in the trigonometric table we include counting fingers, for the cos table we fill in the values in reverse order.
Example 1: Unfortunately 0° has no fingers to the left, so we take 0. Zero divided by 4 gives us 0. Taking the square root of the ratio we get sin value 0° = 0
Example 2: There are 3 fingers to the left of the sentence 60°. 3 by 4 parts we get (3/4). By taking the square root of the ratio √(3/4) we get the value sin 60° = √3/2.

The angles 0°, 30°, 45°, 60° and 90° in the trigonometric table are called standard angles and the trigonometric values of these standard angles are commonly used to solve trigonometric problems. These values relate to the measurement of the lengths and angles of a right triangle.
Undefined values in the trigonometric table are often given the value of infinity (∞) because the value is so large that there is no exact value to give at this time.
Trigonometric functions are defined as functions of the angle of a right triangle. There are 6 basic types of trigonometric functions or ratios used in the trigonometric table,
All the trigonometric functions in the trigonometric table are related to the ratios of the sides of the triangle and their values can be easily found by using the following relations:
