Trigonometry Table Class 10
The Trigonometry Table is useful in science, navigation, and engineering. The invention of the trigonometric table resulted in the creation of the first mechanical computer machines.

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, few formulas 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

- 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
