TL;DR

Derivation and calculations for finding the Taylor series expansion of tan inverse x about x=1.

Transcript

hello everyone in this session we'll see another question on taylor series expansion and it says find the taylor series of tan inverse of x about x is equal to one so about a point x equal to 1. so this is nothing but a is equal to 1 and we can take h is equal to x minus 1 so f of x can be given as f of a plus x minus e f dash of a if double dash a...
