Excellent Trigonometry Books For IIT

is this good enough....??
practicing this book along with R.D.Sharma...is it sufficient for jee trigonometry?

best is study theory(if any) from k.c.sinha and solve new pattern iit jee.....if can solve all the sums of new pattern then you are done....(atleast for iit jee)

k.c.sinha trigonometry and new pattern iit jee mathematics....i guess...
anyways....thanx

K,C sinha is good.

kc sinha trigonometry naa??

all the 4 parts r relatively good (trigo,calcu,co-ordinate, algeb)

ok thanx
