# Mathematics — NCERT Class 12 — CBSE (NCERT textbooks) — Shishya school context > Subject page: https://shishya.in/schooling/cbse/class-12/mathematics · class: https://shishya.in/schooling/cbse/class-12 (context: https://shishya.in/schooling/cbse/class-12/context.md) · data as of 2026-10-11 (IST). Free to cite; link back to the subject page. > Honesty: Shishya never reproduces, summarises or translates textbook text — read a chapter at its official link. Practice questions are Shishya's own, written by AI and answer-checked before they are shown; they are not NCERT exercises, not board questions and not previous-year questions. A chapter marked "not ready yet" has no Shishya notes or practice, and its Shishya page is not linked here. > Children: Class 1-7 school pages have no chat tutor, offer no sign-in and ask no child to create an account. On Class 8-12 pages a student may sign in to save practice to an account — for students 13 and above; no school page asks anyone their age or role — and anyone can read a chapter, take its practice where the chapter has one and ask the AI tutor about it without signing in; the tutor says it is an AI and answers study questions only, with a daily message limit. The 5-question practice on the chapter pages that have it needs no account, and no result is saved to any account or profile from it: Shishya records only an anonymous usage event (which chapter was practised and the score) — on Class 8-12 pages with the same cookie-based analytics every page view sends, on Class 1-7 pages with no cookie, account or other visitor identifier. A signed-in student's own practice set is saved to that account. ## Mathematics - Book: Mathematics Part-I — https://ncert.nic.in/textbook.php?lemh1=0-6 (NCERT also lists Hindi, Urdu editions) - Book: Mathematics Part-II — https://ncert.nic.in/textbook.php?lemh2=0-7 (NCERT also lists Hindi, Urdu editions) - Chapters (13; 13 with Shishya notes, 13 with answer-checked practice of 5+ questions): - Chapter 1 — Relations and Functions — Shishya notes + 39 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/relations-and-functions · official PDF: https://ncert.nic.in/textbook/pdf/lemh101.pdf - Chapter 2 — Inverse Trigonometric Functions — Shishya notes + 36 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/inverse-trigonometric-functions · official PDF: https://ncert.nic.in/textbook/pdf/lemh102.pdf - Chapter 3 — Matrices — Shishya notes + 34 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/matrices · official PDF: https://ncert.nic.in/textbook/pdf/lemh103.pdf - Chapter 4 — Determinants — Shishya notes + 31 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/determinants · official PDF: https://ncert.nic.in/textbook/pdf/lemh104.pdf - Chapter 5 — Continuity and Differentiability — Shishya notes + 39 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/continuity-and-differentiability · official PDF: https://ncert.nic.in/textbook/pdf/lemh105.pdf - Chapter 6 — Application of Derivatives — Shishya notes + 39 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/application-of-derivatives · official PDF: https://ncert.nic.in/textbook/pdf/lemh106.pdf - Chapter 7 — Integrals — Shishya notes + 40 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/integrals · official PDF: https://ncert.nic.in/textbook/pdf/lemh201.pdf - Chapter 8 — Application of Integrals — Shishya notes + 30 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/application-of-integrals · official PDF: https://ncert.nic.in/textbook/pdf/lemh202.pdf - Chapter 9 — Differential Equations — Shishya notes + 38 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/differential-equations · official PDF: https://ncert.nic.in/textbook/pdf/lemh203.pdf - Chapter 10 — Vector Algebra — Shishya notes + 36 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/vector-algebra · official PDF: https://ncert.nic.in/textbook/pdf/lemh204.pdf - Chapter 11 — Three Dimensional Geometry — Shishya notes + 34 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/three-dimensional-geometry · official PDF: https://ncert.nic.in/textbook/pdf/lemh205.pdf - Chapter 12 — Linear Programming — Shishya notes + 34 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/linear-programming · official PDF: https://ncert.nic.in/textbook/pdf/lemh206.pdf - Chapter 13 — Probability — Shishya notes + 34 answer-checked practice questions: https://shishya.in/schooling/cbse/class-12/mathematics/probability · official PDF: https://ncert.nic.in/textbook/pdf/lemh207.pdf - Shishya content last updated: 2026-10-01 ## Other subjects in this class - Physics: https://shishya.in/schooling/cbse/class-12/physics - Accountancy: https://shishya.in/schooling/cbse/class-12/accountancy - Sanskrit: https://shishya.in/schooling/cbse/class-12/sanskrit - Hindi: https://shishya.in/schooling/cbse/class-12/hindi - English: https://shishya.in/schooling/cbse/class-12/english - Biology: https://shishya.in/schooling/cbse/class-12/biology - History: https://shishya.in/schooling/cbse/class-12/history - Geography: https://shishya.in/schooling/cbse/class-12/geography - Psychology: https://shishya.in/schooling/cbse/class-12/psychology - Sociology: https://shishya.in/schooling/cbse/class-12/sociology - Chemistry: https://shishya.in/schooling/cbse/class-12/chemistry - Political Science: https://shishya.in/schooling/cbse/class-12/political-science - Economics: https://shishya.in/schooling/cbse/class-12/economics - Business Studies: https://shishya.in/schooling/cbse/class-12/business-studies - Home Science: https://shishya.in/schooling/cbse/class-12/home-science - Urdu: https://shishya.in/schooling/cbse/class-12/urdu - Creative Writing & Translation: https://shishya.in/schooling/cbse/class-12/creative-writing-and-translation - Fine Art: https://shishya.in/schooling/cbse/class-12/fine-art - Computer Science: https://shishya.in/schooling/cbse/class-12/computer-science - Informatics Practices: https://shishya.in/schooling/cbse/class-12/informatics-practices - Biotechnology: https://shishya.in/schooling/cbse/class-12/biotechnology - Sangeet: https://shishya.in/schooling/cbse/class-12/sangeet
