Problems covered in this video from the Concise Mathematics (ICSE) Selina Publication 2025 Exercise 21 A

1. (secA-1) / (secA+1) ​= (1-cosA) / (1+cosA​)
2. 1 / (tanA+cotA) ​= sinA cosA
3. tanA - cotA = (1 - 2cos²A) / (sinA cosA)
4. cosec⁴ A - cosec² A = cot⁴ A + cot² A

These questions are important for ICSE and CBSE Class 10 board exams.

📝 Time line:
0:00 - Introduction
0:16 - (secA-1) / (secA+1) ​= (1-cosA) / (1+cosA​)
1:27 - 1 / (tanA+cotA) ​= sinA cosA
2:33 - tanA - cotA = (1 - 2cos²A) / (sinA cosA)
3:58 - cosec⁴ A - cosec² A = cot⁴ A + cot² A
