I am sorry for not updating and really sorry since I am going to put the book on hold.

I don't know for how long but I will try to start updating after may.

Don't hate me. I am lacking behind in my studies precisely math. That freaking limit, continuity and differentiability isn't getting in my head. I didn't study class 11 trigonometry and limit chapter so now it's really hard for me.

So please give me few day.

And I am especially sorry to AayushiGhosh .  You asked me twice when I'll update and I even replied for today, I swear I have written the chapter but it's not worthy enough to be uploaded. I just want to finish the first book of math then I will be back.

Till then bye.

I am deeply sorry once again.
