Explanation Definition used: The first order linear equation is of the form d y d t + p ( t ) y = g ( t ) where p and g are function of the independent variable t . Formula used: The integrating factor μ ( t ) of the first order differential equation d y d t + p ( t ) y = g ( t ) is given as μ ( t ) = exp ∫ p ( t ) d t and the solution of the differential equation is given by y = 1 μ ( t ) [ ∫ μ ( s ) g ( s ) d s + c ] . Calculation: The given differential equation is y ′ − y = 1 + 3 sin t with the initial value y ( 0 ) = y 0 . By comparing the equation y ′ − y = 1 + 3 sin t with its standard form d y d t + p ( t ) y = g ( t ) , it is obtained that p ( t ) = − 1 and g ( t ) = 1 + 3 sin t . Compute the integrating factor μ ( t ) of the differential equation y ′ − y = 1 + 3 sin t as follows. μ ( t ) = exp ∫ p ( t ) d t = exp ∫ − 1 d t = e − t Now the solution of the differential equation y ′ − y = 1 + 3 sin t can be obtained by substituting the integrating factor in the formula y = 1 μ ( t ) [ ∫ μ ( s ) g ( s ) d s + c ] as follows
