In summary, integration is a mathematical concept used to find the total or net value of a quantity over a certain interval by finding the anti-derivative of a function. Solving integration homework helps to practice and improve understanding of concepts and techniques, as well as develop problem-solving skills. To solve a homework problem on integration, one must identify the type of integral and apply an appropriate technique. Common mistakes to avoid include forgetting the constant of integration, making errors in algebra or trigonometry, and not paying attention to limits. To improve skills in solving integration homework, it is important to practice regularly, seek help from resources, and understand underlying concepts.

Homework Statement



[tex] \int \frac{sin(\sqrt{x})}{\sqrt{x}} dx [/tex]

Homework Equations


The Attempt at a Solution



I'm not too sure how to approach this. The only thing that rings a bell at this moment is

[tex] \lim_{x\to\0} \frac{sinx}{x} = 1 [/tex]

and I don't feel that it is of any relevance.

Thanks

Use the substitution u = √x. Whats du?
 
  • #3
So [tex] du = \frac{dx}{2\sqrt{x}} [/tex]

[tex] 2 \int sin(u) du [/tex]

Cool, thanks.
 

1. What is integration?

Integration is a mathematical concept used to find the total or net value of a quantity over a certain interval. It involves finding the anti-derivative of a function, which is the function that when differentiated, gives the original function.

2. What is the purpose of solving homework on integration?

The purpose of solving homework on integration is to practice and improve our understanding of the concepts and techniques involved in finding integrals. It also helps to develop problem-solving skills and critical thinking.

3. How do you solve a homework problem on integration?

To solve a homework problem on integration, we first need to identify the type of integral we are dealing with and choose an appropriate technique to solve it. This can involve using properties of integrals, integration by substitution, integration by parts, or other methods. We then apply the chosen technique and simplify the integral until we reach a solution.

4. What are some common mistakes to avoid when solving integration homework?

Some common mistakes to avoid when solving integration homework include forgetting to add the constant of integration, making errors in algebra or trigonometry, and not paying attention to the limits of integration. It is also important to check our work and ensure that our solution makes sense in the context of the problem.
