Solve the Differential Equation Using the Method of Variation of Parameters

question 25

Multiple Choice

Solve the differential equation using the method of variation of parameters. $$y ^ { tt } + y = \sec x , \frac { \pi } { 4 } < x < \frac { \pi } { 2 }$$

• A) \(y ( x ) = c _ { 1 } + \left[ c _ { 2 } + \ln ( \sin x ) \right] \sin x\)
• B) \(y ( x ) = \left( c _ { 1 } + x \right) \sin x + c _ { 2 } + \ln ( \cos x )\)
• C)\(y ( x ) = \frac { \pi } { 2 } \sin x + \left[ \frac { \pi } { 2 } + \ln ( \cos x ) \right] \cos x\)
• D)\(y ( x ) = \left[ \frac { \pi } { 4 } + \ln ( \cos x ) \right] \cos x\)
• E) \(y ( x ) = \left( c _ { 1 } + x \right) \sin x + \left[ c _ { 2 } + \ln ( \cos x ) \right] \cos x\)

Definitions:

Total Cost

The sum of all costs incurred by a business in the production of goods or services, including both fixed and variable costs.

Marginal Cost

The additional cost incurred from producing one more unit of a good or service.

Average Total Cost

A firm’s total cost divided by output (the quantity of product produced); equal to average fixed cost plus average variable cost.

Economies of Scale

Cost advantages that a business obtains due to expansion, leading to a reduction in the average cost per unit through increased production.
