# How to Remember and Write Trigonomery Tables If You Know One

In previous lessons we learned to find the trigonometric ratios like Sine, Cos, Tan etc of 0 degree, 30 degree, 45 degree, 60 degree & 90 degree.

Now we are summarizing this ratios in a single table in this lesson!

This is really a wonderful **trick to remember all the trigonometry table** & write them too.

If you know one trigonometric table either of Sin or Cos then you can easily learn and memorize all the trigonometric ratios Sine, Cos, Tan, Cot. Cosec & Sec for all different angles like

0 degree, 30 degree,45 degree,60 degree & 90 degree.

So make ready your notebook and pen to learn a very smart trick to write all the trigonometry table from 0 to 90 degree.

Get Excited ! Lets begin !

Okay ! So how was it?

How to write – remember trigonometry table ?

1. First make the tables as shown in video or picture below!

2. Write all the ratios of Sin in the table from 0 degree to 90 degree.

3. In the table of Cos – write in opposite order of Sine means in the place of Cos 0 put the value of Sin 90, in Cos 30 put Sin60 like this…

4. In the table of Tan – write the ratios of Sin’ s table and Cos’s table.

5. In the table of Cosec – write the reciprocal value of Sine Table.

6. In the table of Sec – write the reciprocal values of Cos Table.

7. In the table of Cot – write the reciprocal values of Tan Table.

Hey ! That’s it . You learned the trigonometry table. Now we are able to do some numerical I mean some problems related to trigonometry tables.

So in our next lesson we are going to solve few problems related to trigonometry tables.
