Solve the differential equation (x ^ 2-1) y '+ 2XY cosx = 0, thank you very much! (x ^ 2-1) y & # 39; + 2XY cosx = 0, the garbled part is the derivative of Y, detailed process

Solve the differential equation (x ^ 2-1) y '+ 2XY cosx = 0, thank you very much! (x ^ 2-1) y & # 39; + 2XY cosx = 0, the garbled part is the derivative of Y, detailed process

The original equation = > dy / DX + 2x / (x ^ 2-1) * y = cosx / (x ^ 2-1) corresponding homogeneous equation: dy / DX + 2x / (x ^ 2-1) * y = 0 separate variables to get 1 / y * dy = - 2x / (x ^ 2-1) * DX two sides integral to get ln | y | = - ln | x ^ 2-1 | + lnc1y = C / (x ^ 2-1). The general solution of non-homogeneous equation is solved by undetermined coefficient method, so that y = C (x) / (x ^ 2-1)
