Question

integral subscript 0 superscript 100   sin invisible function application left parenthesis x minus left square bracket x right square bracket right parenthesis pi d x

  1. 100 over pi
  2. 200 over pi
  3. 100 pi
  4. 200 pi

hintHint:

We are aware that differentiation is the process of discovering a function's derivative and integration is the process of discovering a function's antiderivative. Thus, both processes are the antithesis of one another. Therefore, we can say that differentiation is the process of differentiation and integration is the reverse. The anti-differentiation is another name for the integration.
Here we have given:  integral subscript 0 superscript 100   sin invisible function application left parenthesis x minus left square bracket x right square bracket right parenthesis pi d x and we have to integrate it. We will use the function method to find the answer.

The correct answer is: 200 over pi


    Now we have given the function as integral subscript 0 superscript 100   sin invisible function application left parenthesis x minus left square bracket x right square bracket right parenthesis pi d x. Here the lower limit is 0 and upper limit is 1. We know that a repeating action that happens at regular intervals is known as a periodic function. So, after a predetermined amount of time, the function returns to its starting place.
    We have:

integral subscript 0 superscript 100   sin invisible function application left parenthesis straight x minus left square bracket straight x right square bracket right parenthesis πdx equals fraction numerator negative 100 over denominator straight pi end fraction cross times left parenthesis negative 1 space minus space 1 space right parenthesis
integral subscript 0 superscript 100   sin invisible function application left parenthesis straight x minus left square bracket straight x right square bracket right parenthesis πdx equals 200 over straight pi

    So here we used the concept of integrals of special functions and simplified it. We can also solve it manually but it will take lot of time to come to final answer hence we used the substitution method to solve. The integral of the given function is integral subscript 0 superscript 100   sin invisible function application left parenthesis straight x minus left square bracket straight x right square bracket right parenthesis πdx equals 200 over straight pi.
