I want some help please.Which book is the best on calculation and analysis among the following; Alexander Kotov Think like A Grandmaster, Andrew Soltis Inner Game of Chess, Jonathan Tisdall Improve your chess now , Jacob Aagard Excellence At Chess Calculation and probably others I want some help from you.

silman is best

Don't know if you've seen Coach Heisman's site but here's a link to his book recommendations:

I agree. Silman is good.

For calculating, you might look at Practical Chess Analysis by Mark Buckley.

I see recommendations for Silman, which seems odd. He is no doubt among the best if you are wanting to learn positional evaluation or endgames, but I'm not sure I recall much from him on the skill of calculating.
