Trigonometric ratio table provided in this section will help you
to find the values of trigonometric ratios for standard angles 0°, 30°,
45°, 60° and 90°.
The values of trigonometric ratios of
standard angles are very important to solve many problems in trigonometry.
First of all let'see the values of Trigonometric ratio for standard angles.

| TRIGONOMETRIC TABLE |
Now, let us see, how the above values of trigonometric ratios are determined for the standard angles.
First, let us see the some simple Trigonometric formulas before see the Tricks to remember the Trigonometric table.
| TRIGONOMETRIC FORMULAS |
Now, We will see the Trigonometric values for all Trigonometric functions one by one.
1. SINE
We remember the sine functions value as it followed by below figure.
| SINE FUNCTION'S VALUE |
2.COS
For, Cos Function’s Trigonometric values we see the below figure. So, According to figure cos function's value is opposite to sin function’s value.
For Example, Sin 0º = Cos 90º , Sin 30º = Cos 60º, …….
| COS FUNCTION'S VALUE |
3.TAN
As, We see the some Trigonometric formulas TAN is the ratio of SIN and COS.
For Example, tan 0º = sine 0º/ cos 0º,
tan 30º = Sine 30º/cos 30º, .......
As per below figure we can determine the TAN function's all angle value .
So, TAN function's value as per below figure.
| TAN FUNCTION'S VALUE |
4. COSEC
As, We see above Cosec function is the reverse of the sine function.So, Cosec function's value is the reverse of the sine function's value.
For Example, Cosec 0º = 1/sine 0º ,
Cosec 30º = 1/Sine 30º, …….
As per below figure we can determine the Cosec function's all angle value .
For Example, Cosec 0º = 1/sine 0º ,
Cosec 30º = 1/Sine 30º, …….
As per below figure we can determine the Cosec function's all angle value .
So, COSEC function's value as per below figure.
| COSEC FUNCTION'S VALUE |
5. SEC
As, We discuss above sec function is the reverse of the cos function.So, Sec function's value is the reverse of the Cos function's value.
sec 30º = 1/cos 30º, …….
As per below figure we can determine the Sec function's all angle value .
So, SEC function's value as per below figure.
| SEC FUNCTION'S VALUE |
5. COT
As, We discuss above cot function is the reverse of the tan function.So, cot function's value is the reverse of the tan function's value.
For Example, cot 0º = 1/tan 0º ,
cot 30º = 1/tan 30º, …….
cot 30º = 1/tan 30º, …….
As per below figure we can determine the Sec function's all angle value .
So, COT function's value as per below figure.
