Hello Dear!!!

Its very easy to remember trigonometry table.

Just learn the values of sin.Then you can easily find all the other values.

Easy trick to learn sin values is-

Angles are 0°,30°,45°,60°,90°.

Start writing numbers from 0,1,2,3,4.
Write these numbers below those angles respectively.

Add '√' to 0,1,2,3,4

The it becomes √0,√1,√2,√3,√4.

Divide these numbers by √4.

Then,
√0/4 , √1/4 , √2/4 , √3/4 , √4/4.

Write these numbers below those angles respectively...

That is √0/4 below 0°
√1/√4 below 30°
√2/√4 below 45°
√3/√4 below 60°
√4/√4 below 90°

So...lets observe 0°.... √0/4....the value is 0.

Now...lets observe 30°....√1/√4...the value of √1 is 1. And √4 value is 2.
Then u will get denominator as 2.
The value is 1/2.

Now...let's observe 45°...√2/√4... The denominator is 2..
The value is 1/√2.

Now,lets observe 60°...√3/√4... The value of √4 is 2.
The value is √3/2.

Now,let's observe 90°... √4/4...after calculation....
The value is 1.



So....you got all the sin values...

If u reverse the order of these values...u will get cos values...

If u divide sin and cos....u will get tan values..

If u reverse the order of tan values
..u will get cot values...

If u do divide...1/sin...u will get cosec values....

If u reverse the order of cosec values...u will get sec values...

What do I mean by reverse the order...

The values for sin are 0,1/2,1/√2 , √3/2,1
Reverse order is 1,√3/2,1/√2,1/2,0.
This is cos.
