U have to look for trigonometric table to find the values. We can only derive for certain values.

You can get the values of all trigonometry functions in log book. Purchase it from any local book store.
Hope it helps.
Thank You.

U need to find from table although
37 degrees is a comonly occuring in questions so just remember the following
37 degree is an angle of a right angle triangle whose sides are 3units. 4 units and 5 units whose base is 4, hypotenuse 5 and perpendicular is 3.
Thus
sin 37 = 3/5
cos 37 = 4/5 and
tan 37 = 3/4
I hope that helps.

You should not be concerned about such things,take it as granted that these are the angles in a right triangle having side of the form 3n,4n,5n,n\inN.

Refer log book.........
 
But my teacher taught me by taking an example of a triangle of side 5 units as hypotenuse and 4 &3 as other sides..
