Just as there are simultaneous algebraic equations (where a pair of numbers have to satisfy a pair of equations) there are systems of differential equations, (where a pair of functions have to satisfy a pair of differential equations). Indicate which pairs of functions satisfy this system. It will take some time to make all of the calculations. y1 = 32 92 = -y1 OA. y1 = 2e-2 y2 = 3e-27 B. 91 = er C. 91 = cos(1) 92 =- sin(I) D. y1= e 92 = e I V E. y1 = er 92 = ez F. y1 = sin(x) + cos(I) y2 = cos(I) - sin(I) G. y1 = sin(x) y2 = COs(I) As you can see, finding all of the solutions, particularly of a system of equations, can be complicated and time consuming. It helps greatly if we study the structure of the family of solutions to the equations. Then if we find a few solutions we will be able to predict the rest of the solutions using the structure of the family of solutions
