can you pls tell me the book which is good for calculus

i think best book for calculus are thomson calculus and objectiv mathematics volume 2 written by rd sharma
 

Depends on what is your goal.

If you goal is to prepare for board exams then you dont need to look beyond NCERT provided you solve all problems includng excempler problems 

If its IIT Mains may be R D sharma is good book.

But if its JEE advanced,  I would recommend Both calculus books from Arihant by Amit Agarwal.

@ karan 
frst of all complete your ncert , then do the exercises as well as miscellenous given in the ncert , then switch up to exempler and solve each and every question their . 
after that choose between the following book , 
but remember to follow any book as calculus is the vast domain of mathematics and every author have diffrent approach to explain the same concept in diffrent manner,,
1- calculus made easy by sylvanous thompson 
2- fundamental of calculus by amit m agarwal 
3- calculus by m l khanna 
4- objective mathematics by r d sharma 
5- calculus formulae by mtg publication 
6- trigonometry fundamental for calculus by s l loney . 
GO FOR THE ONE THAT SUITS YOU THE BEST AND EVERY BOOK IS GOOD , COMPLETET ANY ONE BOOKS PROPERLY AND U ARE ALL SET TO CARCK COMPETETIVE EXAMS . 
ALL THE BEST ../
