Trigonometric table📐....

 After reading the previous blog of trigonometry and hope you have completed the questions without any doubt.....

Let's go for another part of trigonometry that is the trigonometric table which include angles of trigonometric functions and their values on that specific angles......

For example : In Sin A if the angle A is 30° than what will be the value of Sin 30° , likewise this topic includes every trigonometric function's angles and values ....

So let me share you the table which is a very important part of trigonometry chapter....

May be it is challenging for you to remember this table so let me give you one trick which will make it easy to learn and remember....

For Sin θ

Angles ->

    0°            30°            45°             60°            90° 

  √0 = 0       √1 = 1       √2 = 1        √3 = √3      √4 = 1 

  √4             √4    2       √4     2       √4      2       √4

For Cos θ

Observe in the above table it is nothing but Reverse of Sin θ ....

For  Tan θ 

Use that formula which you have learn in previous blog i.e. 

                  Tan θ  =    Sin θ  /  Cos θ

For  Cosec θ  =    1  /  Sin θ

For  Sec θ =  1 /  Cos θ

For  Cot θ  =   1   /   Tan θ

And also keep in mind some minor things i.e.,

                                0 / 1  =  0

                                1 / 0  = Not Defined

 Reciprocal of Not Defined  =  0

I hope now it will be easy for you to remember this and to solve the questions given below 👇🏼..

Questions :

1.    Sin 30°  /  Cos 60°

2.    Sin 30° Cosec 30° 

3.    Cot 45° Sin 90° + Tan 45° Cos 0°

4.    1 / Sin 45°

5.    Cos 45° / Sin 45°

Try these questions for more understanding and if unable to solve the questions than comment down.....

And also try to solve these problems without looking in the table......
