Final answer:

Without the specific homogeneous equation, we can't show that y1 = t and y2 = t^2 are solutions. Generally, to verify solutions, we substitute them into the equation, simplify, and check for equality. This method applies to verifying solutions for various differential equations, including wave equations.

Step-by-step explanation:

The question provided asks to show that y1 = t and y2 = t^2 solve the corresponding homogeneous equation. However, without the specific form of the homogeneous equation provided, we cannot directly show that these functions are solutions. Nonetheless, we can elaborate on the general procedure to verify solutions to a homogeneous equation.

To verify that a particular function is a solution to a differential equation, we would typically follow these steps:

  • Identify the differential equation that needs to be solved.
  • Substitute y1 and y2 into the homogeneous equation.
  • Simplify the equation to check whether the left-hand side equals the right-hand side.
  • If both sides of the equation are equal after the substitution and simplification, then y1 and y2 are indeed solutions to the equation.

For example, if the homogeneous equation is of second order, say Ay'' + By' + Cy = 0, you would compute the first and second derivatives of y1 and y2, substitute them into the equation, and then confirm if the result is zero. In this way, you can demonstrate that these functions are solutions to the equation.

This procedure also applies to linear wave equations and their associated principles, such as the principle of superposition, where the linear combination of solutions is itself a solution.
