JEE Main 2026 Physics question
Match List-I with List-II. List-I: A. sin²ωt, B. sin³(2ωt), C. sin(ωt)+cos(πωt), D. cosωt+cos2ωt. List-II: I. Periodic with time period T=π/ω but not simple harmonic motion (SHM), II. Periodic with time period T=2π/ω but Not SHM, III. Periodic with time period T=π/ω and SHM, IV. Non-periodic.
Answer: (A)
Solution
sin²ωt=½−½cos2ωt is a shifted single-frequency cosine (period π/ω, SHM about a shifted mean): A-III. sin³(2ωt) is a combination of two different frequencies with period π/ω but
