CBSE Class 12 Mathematics 2026 Supplementary Paper 65/7/3 · Question 13 (Integrals)
Evaluate \(\int e^x(2+\sin2x)/(1+\cos2x)\,dx\).
✅ Step-by-Step Solution
Final Answer: eˣ tan x+C
- The rational trigonometric factor is sec²x+tan x on the domain. By the product rule this makes the integrand the derivative of eˣ tan x.
