# Find {eq}f {/eq} given the following information: {eq}f''(x) = 4cos(x), f'(\pi/2) = 0, \; f(0) = 5 {/eq}.

## Question:

Find {eq}f {/eq} given the following information: {eq}f''(x) = 4cos(x), f'(\pi/2) = 0, \; f(0) = 5 {/eq}.

## Indefinite Integration:

Generally, we can define indefinite integration as the reverse process of the derivative of a function. In other words, we can mention this process is an anti-derivative. For example, the result of the integration of the derivative is the function with the constant.
