Trigonometry Table PDF Summary

Dear readers, here we are offering Trigonometry Table PDF to all of you. Trigonometry is a branch of mathematics under which the relationship between the sides and angles of a triangle is studied. Trigonometry is found throughout geometry since every straight-sided figure can be broken down into a collection of triangles. Furthermore, trigonometry has surprisingly complex relationships with other branches of mathematics, especially complex numbers, infinite series, logarithms, and calculus. Here all the Trigonometry Formulas for Class 10 and Trigonometry Formulas for Class 11th are given which can be helpful for the preparation in Classes 10th and 12th also. Questions related to Trigonometry are asked in various competitive exams like SSC, Railway, etc. In this post, we are providing you with helpful Trigonometry Notes for the examinations. This will help you to remember the basic formulas of trigonometry.

How to Learn Trigonometric Table?

The trigonometric table might seem complex at first, but it can be learned easily by only the values of sine for the 8 standard angles. Before generating the table, there are few formulas that must be followed as given below:

tan x = sin x/cos x

cosec x = 1/sin x

sec x = 1/cos x

cot x = 1/tan x

Trigonometry Table 0-360 Value Formulas

sin x = cos (90° – x)

cot x = tan (90° – x)

sec x = cosec (90° – x)

cos x = sin (90° – x)

tan x = cot (90° – x)

cosec x = sec (90° – x)

1/sin x = cosec x

1/tan x = cot x

1/cos x = sec x

Periodicity Identities (in Radians)

These formulas are used to shift the angles by π/2, π, 2π, etc. They are also called co-function identities.

sin (π/2 – A) = cos A & cos (π/2 – A) = sin A

sin (π/2 + A) = cos A & cos (π/2 + A) = – sin A

sin (3π/2 – A)  = – cos A & cos (3π/2 – A)  = – sin A

sin (3π/2 + A) = – cos A & cos (3π/2 + A) = sin A

sin (π – A) = sin A &  cos (π – A) = – cos A

sin (π + A) = – sin A & cos (π + A) = – cos A

sin (2π – A) = – sin A & cos (2π – A) = cos A

sin (2π + A) = sin A & cos (2π + A) = cos A

All trigonometric identities are cyclic in nature. They repeat themselves after this periodicity constant. This periodicity constant is different for different trigonometric identities. tan 45° = tan 225° but this is true for cos 45° and cos 225°. Refer to the above trigonometry table to verify the values.

Cofunction Identities (in Degrees)

The co-function or periodic identities can also be represented in degrees as:

sin(90°−x) = cos x

cos(90°−x) = sin x

tan(90°−x) = cot x

cot(90°−x) = tan x

sec(90°−x) = cosec x

cosec(90°−x) = sec x

What is a trigonometry table?

A trigonometry table is a table of values of trigonometric functions such as sine, cosine, tangent, cosecant, secant, and cotangent, for different angles.

What is a trigonometry table PDF?

A trigonometry table PDF is a digital format of the trigonometry table that can be easily downloaded, printed, and used for reference.

What is the use of a trigonometry table PDF?

A trigonometry table PDF is used as a reference for calculating trigonometric functions for different angles without the need for a calculator.

How is a trigonometry table PDF helpful for students?

A trigonometry table PDF is helpful for students studying trigonometry as it allows them to quickly and easily look up trigonometric function values for different angles, which can help in solving problems and understanding concepts.

What are the angles typically included in a trigonometry table PDF?

A trigonometry table PDF typically includes angles ranging from 0 to 90 degrees, or 0 to π/2 radians.

Can a trigonometry table PDF be used for angles greater than 90 degrees?

No, a trigonometry table PDF typically only includes values for angles between 0 and 90 degrees. To calculate values for angles greater than 90 degrees, one can use the identities of trigonometric functions to simplify the calculations.

Are there different formats of trigonometry table PDFs available?

Yes, there are different formats of trigonometry table PDFs available, such as full-page tables, pocket-sized tables, tables with only selected values, etc.

Are there any online resources available for accessing trigonometry tables?

Yes, there are many online resources available for accessing trigonometry tables, such as educational websites, math forums, and digital libraries.

How accurate are trigonometry tables?

Trigonometry tables are accurate to a certain degree, but the accuracy can be limited by factors such as the degree of rounding used in the table, errors in calculations, and errors in printing.

Can a trigonometry table PDF be used in exams?

The use of trigonometry table PDFs in exams varies depending on the exam regulations and requirements. It is important to check the rules and guidelines before using a trigonometry table PDF in an exam.
