Some problems may have NO constraint equation. The constraint equation is used to solve for one of the variables. Lambda2 - 4lambda 4 0 implies lambda - 22 0 Repeated roots mean that in lieu of the usual solution y_c alpha elambda_1 x beta elambda_2 x we look here for a solution in the form.
One equation is a constraint equation and the other is the optimization equation.
Some problems may have two or more constraint equations. Solve the Linear Equation of Single Variable. If eqn is a symbolic expression without the right side the solver assumes that the right side is 0 and solves the equation eqn 0. Y_g e2 x x2 2 x 1 Method of Undetermined Coefficients Start with the homogeneous equation and the complementary solution.
