Appears frequently. Series expansions of sin x, cos x, eˣ and ln(1 + x) to the x³ term save a lot of time.
Chapter names follow the current rationalised NCERT textbooks. Read these sections before solving PYQs.

Question. Evaluate lim(x→0) [(e^(sin x) - e^(tan x)) / x³]
Answer: -1/2
This example was solved twice independently and both solutions agree.
Full-chapter free lectures picked from YouTube search results by views, from established JEE channels (mostly in Hinglish). Use the subtopic list to jump straight to the part you need (timestamps come from each video's own chapter list). Watch one, then solve PYQs the same day.
Appears frequently. It is part of the official 'Limit, Continuity and Differentiability' unit in the JEE Main 2027 syllabus.
lim sin x / x = 1, lim (1 − cos x)/x² = ½; lim (eˣ − 1)/x = 1, lim ln(1 + x)/x = 1; lim (1 + x)^(1/x) = e.
Understand the key ideas from NCERT or one full lecture, learn the formula sheet, then solve 25–30 past JEE questions on the topic. Series expansions of sin x, cos x, eˣ and ln(1 + x) to the x³ term save a lot of time.
