Program Explanation Given information: The system of differential equations is, x ′ = t x − y + e t z , y ′ = 2 x + t 2 y − z and z ′ = e − t x + 3 t y + t 3 z Explanation: The given system of differential equations is, x ′ = t x − y + e t z , y ′ = 2 x + t 2 y − z and z ′ = e − t x + 3 t y + t 3 z The above equation in matrix equation is written as, x ′ ( t ) = [ x ′ y ′ z ′ ] = [ t x − y + e t z 2 x + t 2 y − z e − t x + 3 t y + t 3 z ] The above matrix can be written in the form of product of matrices as, x ′ ( t ) = [ x ′ y ′ z ′ ] = [ t 1 e t 2 t 2 − 1 e − t 3 t t 3 ] [ x y z ] + [ 0 0 0 ] Therefore, x ′ ( t ) = [ t 1 e t 2 t 2 − 1 e − t 3 t t 3 ] [ x y z ] + [ 0 0 0 ]
