Dear Jaivanth

Not particularly, but yes they are part of JEE syllabus because there are questions in JEE MAINS and ADVANCE basis on logarithim, so you must have clear idea , about how to use log and its graph , because its basics will always be there in problems.

There is a topic in NCERT called logarithmic differentiation , it will help you get clear understanding.

For solving many problems in JEE you have to know about logarithmic properties.

So keep practicing

Thankyou

Hello..!

For getting appreciable results and clearing your basics, you need to study it.

Most of the coaching institutes also teach it in their curriculum.

It may or may be not be in their syllabus, but studying it brings you on safer side.
