Incorrect Question 1 0/1 pts A system of 3 simultaneous linear second order ordinary differential equations can be written in a matrix form with the coefficient matrix of size 8 x 8 6x6 2x2 3 x 3 4x4 Incorrect Question 7 0/1 pts When solving systems of linear ordinary differential equations, fractional coefficients frequently arise. It is easier to obtain the correct solution by using a calculator to replace fractions with their decimal representation consistently keeping track of fractional values throughout algebraic manipulations with no back and forth symbolic substitution introducing single-character notation for fractional values, performing the necessary algebraic manipulations with them and re- introducing the fractions in the final symbolic answer
