suggest some good book for 3d geometry and vectors. using multiple books for maths really help (like loney, hall and knight ia maron etc)or i should prepare using a single book like ml khanna or tmh?

Dear shanshank

I will suggest you to go for multiple books.because generally a single books doesnot have all the chapter well explained.

For vector and 3D geometry refer IIT MATHA by M L KHANNA.
