Hope it helps.

I m writing the trick to learn trigonometric values:

       0*        30*         45*         60*         90*

1.Sin   0           1              2            3            4    {Write no from 0-4

2.        0/4       1/4           2/4        3/4          4/4   {Divide the whole by 4}

3.    root(0/4)  root(1/4)..........................................   {Apply root}

4.         0/2      1/2           root2/2    root3/2    1

5         Reciprocal it like 0*=1 and so on...{Tis will give u Cos}

6.         Divide Sin/Cos    like   Sin0*/cos 0* will give u Tan 0* and soo onn.  

                                          Hope it helps!!
