Math Problem Statement

y=c1e^x+c2e^(5x)

Solution

The equation you've provided is a general solution to a second-order homogeneous linear differential equation with constant coefficients. The general form of such a solution is typically:

y=c1eα1x+c2eα2xy = c_1 e^{\alpha_1 x} + c_2 e^{\alpha_2 x}

In your case, the solution is:

y=c1ex+c2e5xy = c_1 e^x + c_2 e^{5x}

Here, c1c_1 and c2c_2 are arbitrary constants, and the exponents xx and 5x5x suggest that the characteristic equation associated with the differential equation has roots 11 and 55.

Explanation:

This function likely solves a differential equation of the form:

y6y+5y=0y'' - 6y' + 5y = 0

Deriving the differential equation:

  1. The characteristic equation for the differential equation can be written as:

r26r+5=0r^2 - 6r + 5 = 0

  1. Solving for rr gives the roots r=1r = 1 and r=5r = 5.

  2. Therefore, the general solution to the differential equation is:

y=c1er1x+c2er2xy = c_1 e^{r_1 x} + c_2 e^{r_2 x}

Where r1=1r_1 = 1 and r2=5r_2 = 5, leading to:

y=c1ex+c2e5xy = c_1 e^x + c_2 e^{5x}

Do you want more details or have any questions?

Here are 5 related questions:

  1. How do you find the roots of the characteristic equation?
  2. What are some initial conditions that could determine the values of c1c_1 and c2c_2?
  3. How can this general solution be applied to a real-world problem?
  4. What happens if the roots of the characteristic equation are complex?
  5. How do you solve a non-homogeneous differential equation?

Tip: For a non-homogeneous differential equation, the general solution is the sum of the homogeneous solution and a particular solution.
