question 134

Multiple Choice

Solve the differential equation using the method of variation of parameters.
$$y ^ { tt } - 4 y ^ { t } + 3 y = 2 \sin x$$

• A)
• \(y ( x ) = c _ { 1 } e ^ { 3 x } + c _ { 2 } e ^ { x } + \frac { 1 } { 5 } \sin x\)
• B)
• \(y ( x ) = c _ { 1 } e ^ { 3 x } + c _ { 2 } e ^ { x } + \frac { 2 } { 5 } \cos x + \frac { 1 } { 5 } \sin x\)
• C)
• \(y ( x ) = c _ { 1 } \sin x + \frac { c _ { 2 } } { 5 } x + \frac { 1 } { 5 } \sin x\)
• D)
• \(y ( x ) = c _ { 1 } \sin 3 x + \frac { c _ { 2 } } { 4 } x + \cos 3 x\)
• E)
• \(y ( x ) = c _ { 1 } e ^ { 3 x } + c _ { 2 } e ^ { x } + \frac { 2 } { 5 } \sin x\)

Definitions:

Correlation Coefficient

A value that quantifies both the magnitude and the direction of a straight-line association between a pair of variables.

Box Plot

A graphical representation of the distribution of a data set, showing the median, quartiles, and outliers, used for depicting the spread and skewness of the data.

Outlier

A data point that diverges significantly from the overall pattern of data in a dataset, potentially indicating a measurement error or a new trend.

IQR

The Interquartile Range (IQR) is a measure of statistical dispersion, being equal to the difference between the 75th and 25th percentiles of a data set.
