Inhomogenous differential equation of second order

Click For Summary
SUMMARY

The discussion focuses on solving the inhomogeneous second-order differential equation \( y^{\prime\prime} + y = \frac{1}{\sin x} \). The solution involves first addressing the homogeneous equation, yielding \( y = C_1 \sin x + C_2 \cos x \). The method of variation of constants is recommended for finding a particular solution, with a specific technique of multiplying the first equation by \( \cos x \) and the second by \( \sin x \) to simplify the system. This approach effectively aids in solving the equation.

The Attempt at a Solution



I solved the homogenous equation: y=C_1\sin x+C_2\cos x, and then I tried to use method of variable the constant. But the equation system is rather hard. Do you know any other method that can be used here?

Yeah, it does. Thanks for your answer. I started to calculate it and I got it. For future visitors: you must multiplicate first equation by \cos x and second by \sin x and try to reduce it.
