- A \(e^x \tan x+C\), where C is a constant
- B \(e^x \sec x+C\), where C is a constant
- C \(e^x \tan \left(\frac{x}{2}\right)+C\), where C is a constant
- D \(e^{-x} \tan \left(\frac{x}{2}\right)+C\), where C is a constant
Answer & Solution
Correct Answer
(C) \(e^x \tan \left(\frac{x}{2}\right)+C\), where C is a constant
Step-by-step Solution
Detailed explanation
\(I=\int e^x\left(\frac{1+\sin x}{1+\cos x}\right) d x\) \(I=\int e^x\left(\frac{1}{1+\cos x} + \frac{\sin x}{1+\cos x}\right) d x\)…
