Find constants and such that . Graph the second component of this solution using the MATLAB plot command. Use pplane5 to compute a solution via the Keyboard input starting at and then use the y vs t command in pplane5 to graph this solution. This gives the two solutions. y1(t) = er1t and y2(t) = er2t. Now, if the two roots are real and distinct ( i.e. r1 ≠ r2) it will turn out that these two solutions are “nice enough” to form the general solution. y(t) = c1er1t + c2er2t. As with the last section, we’ll ask that you believe us when we say that these are “nice enough”.$\begingroup$ @potato, Using eigenvalues and eigenveters The general solution is a linear combination of these three solution vectors because the original system of ODE's is homogeneous and linear. ...
