For the differential equation dy/dx + (cos x)y = sin x cos x, the integrating factor is:
For the differential equation dy/dx + (cos x)y = sin x cos x, the integrating factor is:
- A. e^(sin x)
- B. e^(cos x)
- C. sin x
- D. cos x
Answer: A) e^(sin x)
Explanation: P = cos x. IF = e^(∫P dx) = e^(∫cos x dx) = e^(sin x).
