Yakeen 3.0 2027 - 1st Free Class of Physics by Tanuj Sir🔥 || NEET 2027

Main ideas / concepts taught

• Welcome + course structure (NEET 2027 “Yakeen 3.0”)

  • This is the first General Physics class for the 2027 batch.
  • The class is initially live on YouTube only.
  • After the first class, recordings/classes appear on the app.

• Why basics matter (Physics starts with Math)

  • The course will teach physics from the very basics.
  • Basic mathematics is essential because:
    • NEET questions are often calculation-based, even if they don’t look like direct math.
    • Physics topics require tools like log, trig, and calculus (differentiation/integration).

• Batch resources & daily practice system

  • The batch will cover the full syllabus without missing topics.
  • Students get:
    • Lectures
    • DPP (Daily Practice Problem)
    • Assignments
    • TPP (Watermelon Practice Problem) — a branded practice sheet/series
    • Homework in every lecture
    • Practice sheets, including separate PYQ-style questions
    • Video solutions (especially referenced for DPP and TPP; some solutions are stated as being prepared by him)

• Discipline-driven success philosophy

  • Students are urged to keep consistent enthusiasm daily, not just on day 1.
  • Core message: motivation is temporary, but discipline + internal drive + routine revision/testing lasts.
  • “No backlog” is emphasized: falling behind causes difficulty to compound.

• Three key pillars

  • Discipline
  • Tests
  • Trust in yourself
  • Tests are framed as necessary to build readiness and reduce fear; even low marks early are considered useful.

• Course approach to teaching

  • Concepts first; short tricks are only secondary support.
  • Trick-based methods are said to fail often; conceptual clarity is treated as the “real weapon.”
  • Teaching style includes:
    • Stepwise progression from basic → advanced
    • Similarity between class examples and exam tests (not “random/surprise-only” difficulty)

Detailed methodology / instructions (explicit list)

A) How the class/batch will run

• Start from basics in every topic.
• Cover the complete syllabus.
• Provide learning materials each day:
  • Lecture content
  • DPP
  • TPP
  • Assignments + practice sheets + PYQ-based questions
  • Homework questions to solve

B) Student responsibilities (daily routine)

• Revise the lecture on the same day (same-day revision is repeatedly emphasized).
• Make notes:
  • Theory must be written (handwritten emphasis).
  • Short notes will be provided, but students should also create their own notes.
  • Typed questions are optional to rewrite; handwritten theory and question tracking are important.
• Solve all assigned work:
  • DPP/TPP/assignments/homework must be done on the same day they’re given.
• Avoid backlog:
  • If lectures are missed, catching up becomes hard.
  • Assignments may be slightly delayed sometimes, but lecture backlog should not happen.
• While solving questions:
  • Always complete calculations to the end (don’t assume “it will get done later”).

C) Test plan guidance

• Students should plan to give many tests (minimum targets like ~100; earlier mentions like 120 for top scorers).
• Tests are expected to be concentrated in March–April.
• Students are encouraged to:
  • Take tests without fear
  • Use test results for improvement rather than avoidance.

D) How questions are to be attempted and tracked

• For revision:
  • Revisit wrong questions and mark mistakes so they get priority later.
• While taking notes:
  • Use lecture number + slide number in fair copy.
  • Theory is mandatory; questions can be handled with handwritten/rough-copy approach depending on time.

Physics lesson content in this lecture: Trigonometry basics (with units/ratios)

1) Angle as the starting concept

• Angle θ is formed between two lines.
• Angle in a circle can be defined using:
  • a circular arc
  • arc length (s)
  • radius (r)
• Key relation:
  • (\theta = \frac{s}{r}) and equivalently (s = r\theta)

2) Units of angle

• SI unit of θ is radian
• Degrees are also used in practice, but SI is radians.

3) Full circle relations

• Full circle arc length is (2\pi r).
• Applying (\theta = s/r):
  • (\theta = 2\pi) radians
  • which equals (360^\circ)
• Therefore:
  • (180^\circ = \pi) radians

4) Trigonometric ratios using a right triangle

• Construct a right-angle triangle with angle θ.
• Define triangle sides relative to θ:
  • Opposite to θ = perpendicular (P)
  • Adjacent to θ = base (B)
  • Hypotenuse = H
• Ratios:
  • (\sin\theta = \frac{P}{H})
  • (\cos\theta = \frac{B}{H})
  • (\tan\theta = \frac{P}{B})
  • (\csc\theta = \frac{H}{P})
  • (\sec\theta = \frac{H}{B})
  • (\cot\theta = \frac{B}{P})
• Reciprocal/inverse relationships are also stressed (e.g., inverse of sin ↔ cosec, etc.).

5) Pythagoras + special “famous right triangle” values

• Pythagoras theorem:
  • (P^2 + B^2 = H^2)
• Common remembered Pythagorean triples:
  • (3,4,5)
  • (5,12,13)
  • (8,15,17)
  • (7,24,25) (as referenced)

6) Using triples to avoid heavy memorization

• If ((a,b,c)) is known, then scaling by a factor scales the triangle sides.
• This helps compute sin/cos/tan quickly in exams.

7) Typical 0° to 90° value table approach

• Standard values for (\sin\theta) at 0°, 30°, 45°, 60°, 90°
• (\cos\theta) obtained by reversing the corresponding order
• (\tan\theta) via division (sin/cos)
• Later extension includes complementary/supplementary ideas and quadrant behavior (negatives for cos/tan appear later).

8) Complementary + supplementary angles

• Complementary angles: sum to 90°
  • sin and cos values interchange
• Supplementary angles: sum to 180°
  • definition is stated by naming (detailed value rules implied later)

9) “Famous angles”: 37° and 53°

• Derived using (3,4,5) triangle logic.
• Key idea:
  • Use triangle ratios rather than rote memorization.
• Mentioned caveat:
  • not exact (small decimal differences), but accepted values are used for NEET-level problems.

10) Quick problem-solving strategy: “which trig ratio to use?”

• A decision rule based on given and required:
  • Perpendicular given, hypotenuse to find → sin θ
  • Base given, hypotenuse to find → cos θ
  • Perpendicular given, base to find → tan θ
• Emphasis: identify the missing side and select the ratio accordingly.

11) Angle of elevation & angle of depression (Physics application)

• Angle of elevation: between a horizontal line and line of sight upwards to a higher point.
• Angle of depression: between a horizontal line and line of sight downwards to a lower point.
• Examples:
  • Tree distance with 60° elevation:
    • use (\tan\theta = \frac{\text{opposite}}{\text{adjacent}}) to find distance.
  • Tree height problem:
    • angles of elevation/depression from a point to top/bottom form equations.
    • final result expressed as the height of the second tree (concluded with option B).
