Teaching DSSSB TGT Mock Test 2025 Engineering Mathematics Differential Equations Higher Order Linear Differential Equations with Constant Coefficients
\({{{d^2}y} \over {d{x^2}}} + 4{{dy} \over {dx}} + 3y = \sin 2x\)
The particular integral for the differential equation is:
1
\({1 \over 7}\sin 2x\)
2
\({{ - 1} \over {65}}\left( {8 \cos 2x + \sin 2x} \right)\)
3
\({{ - 1} \over {65}}\left( {4\cos 2x + \sin 2x} \right)\)
4
\({1 \over 7}\left( {\sin 2x + 2\cos 2x} \right)\)
