make a chart of all the results and stick them on your bedroom wall...or the place you spend most of your time in when at home...once or twice a day, glance through all the formulae and just repeat them to yourself...you should be able to remember all the formulae in ten days or so..

it worked really well for me...

make a chart like this

sin        0           30         60         45           90

o/41/2   1/41/2   2/41/2   3/41/2     4/41/2

make the sq. rt.( squar root) of angels opp. in  cos

cos     0            30           60         45         90

4/41/2    3/41/2    2/41/2    1/41/2    0/41/2

divide both sin and cos to get tan--- sino/ coso

THERE RE MANY WAYS, BY WHICHU CAN BE ABLE TO GET UR FORMULAS IN UR MIND. BUT ALL OF THESE REQUIRES SINCERE DEVOTION.

1) MAKE TABLES AND REVISE THEM ON DAILY BASIS.

2) EITHER U CAN LEARN TO DERIVE THEM AND USE THEM INITIALLY. AS U WILL BE USED TO DERIVATION, FORMULAS WILL AUTOMATICALLY  FIT INTO UR MIND.

AND M,OST IMP. PRACTISE AS MANY QUESTIONS AS U CAN.

There is a good way to learn trignometric formula and use them like a wizard.First don't memorize them ,but you should know how it came,except the sin(a+b) like that ones which you should know.The other all formulas can be derived from the a+b formulas.Now take your time is doing problems of trignometry every time you may not be knowing the formulas, but you know to derive it whoila!! derive it everytime you need.Thereby you will surely understand how that works well and after a short intrevel of time you will surely remember the formula.Not just simple memorizational memory but a conceptual memory.Try it and click like
