Hi Aishwarya -

* Math is all about practice. 
* Which trigonometric functions are you specifically requiring help ?

Always remember that the sin/cos/tan are just different representations of important ratios that we see commonly occuring in nature - and instead of typing ratios for different angles, we use these formulaes to make life easier.

Here is an interesting practical fun idea to do at home -

Get a protractor and place it standing up 2 ft in front of a wall. Lie down and approximately see what angle is made from the protractor to the top of the wall. Now with these two measurements ( the angle and the horizontal distance to the wall ), find the height of the wall. 
Now imagine standing in front of the Eiffel tower. You can measure the height ( approximately ) of Eiffel tower without climbing it and with just a protractor and a measuring tape ( for horizontal measurement ). Isnt that cool ???

Now you can extrapolate and measure distances to planets, stars etc. And this is just the start of the use of trigonometry...

Once you get fascinated by this exercise, you will learn these formulaes easily. I will try to come up with practical uses of each of these formulaes in a later post.

You can begin with by trying to understand why these functions exist here

Start practicing 2 problems a day. More importantly see in a real world where these functions are applied. That will get you excited to learn more.

Here is a wikihow link to take you through this step by step. When you are done, use our CBSE 11th Math  to practice more or click on the "P" button in clay6 CBSE 11th study plan - trigonometric functions chapter - to practice in a step by step manner. That will ease the process to learn. Have a cheat sheet of formulas from your book. 


Have fun...
