Class 12 ka pehla unit — functions ke types samjho, inverse trig explore karo. 8 marks board exam mein.
Reflexive, symmetric, transitive aur equivalence relations. One-one, onto, bijective functions. Composition of functions.
Read Chaptersin⁻¹, cos⁻¹, tan⁻¹ — domain, range, principal value. Important properties aur identities. Graphs aur transformations.
Read ChapterFunctions ko visually explore karo — bijective test, inverse trig graph plotter, aur MCQ missions.
Open LabIs unit mein 2-mark aur 3-mark questions aate hain. Composition of functions aur inverse trig identities (jaise sin⁻¹x + cos⁻¹x = π/2) zaroor yaad rakho. Bijective function ka proof likhna practice karo.
