Change and approximation
Calculus studies how a quantity changes and how small changes accumulate. Graphical interpretation should accompany the notation.

Όρια και συνέχεια: structured theory, worked examples, answered practice, and a mastery checklist for Greek Lyceum Grade 3.
Unit
The essential chapter ideas in a clear sequence before practice.
Calculus studies how a quantity changes and how small changes accumulate. Graphical interpretation should accompany the notation.
Check domain, continuity, or differentiability where required. A correct rule cannot be applied mechanically outside its conditions.
A derivative represents local rate of change and a definite integral represents net accumulation. Always reconnect the result to the original problem.
Mathematics
Follow the method step by step and check why every step is valid.
For f(x) = x³ - 2x, find the derivative and the gradient at x = 4.
Mathematics
A full programme: official syllabus, theory, methodology, topic exercises, mocks, and systematic error correction.
The structure follows the official textbook layout and is used to organise study.
f'(x) = 3x² - 2, f'(4) = 46
Before calculating, explain the key idea from “Όριο σε σημείο” and which conditions must be checked.
The answer should show not only which rule is used for “Όριο σε σημείο”, but also why it is valid here.

Try independently, use the hint if needed, then open the answer guide.
1. Explain the idea and give one correct foundation example for “Όριο σε σημείο”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Όριο σε σημείο”, shows equivalent steps, and includes a final check.
2. Solve an application and show every intermediate step for “Πλευρικά όρια”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Πλευρικά όρια”, shows equivalent steps, and includes a final check.
3. Compare a correct and an incorrect approach and justify the difference for “Πράξεις ορίων”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Πράξεις ορίων”, shows equivalent steps, and includes a final check.
4. Create a short exam-style question and check your answer for “Άπειρα όρια”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Άπειρα όρια”, shows equivalent steps, and includes a final check.
The areas that usually create mistakes or need extra revision.
Where to start: textbook, daily material, PDFs, videos, and worked examples.
Targeted practice before full tests so coverage is clear.
