Determine whether the improper integral converges or diverges, and find the value of each that converges.
∫^[infinity]_-[infinity] x/x^2+1 dx

Converges to 0

Step-by-step explanation:

Given is an improper integral  where a= -infinity, b = infinity and

f

This resembles the above integral where a = -b

f(x) let us check whether odd or even or neither

=-f(x)

Since f(x) is odd function and integral is of the form -a to a by properties of integrals, this value is 0

Hence answer is 0

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

the answer to that one is b
