If sec θ + tan θ = x, then sec θ − tan θ = ? CBSE Sample Paper 2025–26 Class 10 Maths ‪@MATHSAJsir‬

Question: If sec θ + tan θ = x, then sec θ − tan θ = ? (A) x  (B) x²  (C) 2/x  (D) 1/x Explanation: 👉 Given: sec θ + tan θ = x We know, (sec θ + tan θ)(sec θ − tan θ) = 1 Now, sec θ − tan θ = 1 / (sec θ + tan θ) Substitute sec θ + tan θ = x ⇒ sec θ − tan θ = 1/x ✅ Final Answer: (D) 1/x Details Section (for video description): 📘 CBSE Class 10 Maths Standard 2025–26 📚 Topic: Trigonometric Identities 👨‍🏫 By A.J.
