# Solve the following by the method of variation of parameter. 1)

### Resolved Question:

Solve the following by the method of variation of parameter.

1) y'' + y = sec(theta) * tan(theta)

2)y'' - y cosh(x)

3) y'' - 2y' + y = e^(x) / (1 + x^(2))

4) 3y'' - 6y' + 6y = e^(x) * sec(x)

Solve the following using the method of undetermined coefficients

1) y'' - 8y' +20y = 100x^(2) - 26xe^(x)

2) y'' - 4y = ((x^2) - 2) * sin(2x)

3) y'' - 2y' +2y = e^(2x) * (cos(x) - 3sin(x))

4) y'' + 2y' - 25y = 16 - (x+2) * e^(4x)
