Class 12 Maths · Continuity And Differentiability · Conceptual Answer #39
Differentiate sec²(x²) with respect to x².
✅ Step-by-Step Solution
Final Answer: 2sec²(x²)tan(x²)
- Set u=x², so d(sec²u)/du=2sec u·sec u tan u=2sec²u tan u.
- 2sec²(x²)tan(x²)
📋 CBSE Stepwise Marking Scheme
- [0.5 marks] Set u=x², so d(sec²u)/du=2sec u·sec u tan u=2sec²u tan u.
- [0.5 marks] 2sec²(x²)tan(x²)
