There are simple tricks to learn it ...
one of them is
remember sin0° and cos0°...for sin90° add the value of cos0° and for cos90° add the value of sin0°.
remember the value of sin30° and cos 30° ...
here, sin60°=cos30° and cos60° = sin30°.
sin45° will b equal to cos45°.
tan45°=cot45°.
sec45=cosec45.
tan30=cot60
cot30=tan60.
sec30=cosec60.
cosec30=sec60
tan0=cot90
cot0=tan90
Read these while looking at table.It would b more helpful.
It just goes diagonally.Notice it...
hope u find it's useful...
