What calculator can do integrals?

Summary: Your TI-83/84 can compute any definite integral by using a numerical process. That can be a big help to you in checking your work.

How do you definite an integral?

If we have a function 𝒇(𝑥) and know its anti-derivative is 𝑭(𝑥) + C, then the definite integral from 𝑎 to 𝑏 is given by 𝑭(𝑏) + C – (𝑭(𝑎) + C).

How do you determine if an integral is improper?

Integrals are improper when either the lower limit of integration is infinite, the upper limit of integration is infinite, or both the upper and lower limits of integration are infinite.

How do you know if an improper integral converges or diverges?

If the limit exists and is a finite number, we say the improper integral converges . If the limit is ±∞ or does not exist, we say the improper integral diverges .

How do you tell if an infinite series converges or diverges?

There is a simple test for determining whether a geometric series converges or diverges; if −1infinite series will converge. If r lies outside this interval, then the infinite series will diverge.

Does limit exist if diverges?

Divergence means the limit doesn’t exist. So yes, a sequence can only converge or diverge, because either there is a limit, or there isn’t.

How do you know if a limit does not exist algebraically?

In order to say the limit exists, the function has to approach the same value regardless of which direction x comes from (We have referred to this as direction independence). Since that isn’t true for this function as x approaches 0, the limit does not exist.

Does the limit exist at a hole?

If there is a hole in the graph at the value that x is approaching, with no other point for a different value of the function, then the limit does still exist.

How do you know if a function diverges?

divergentIf a series does not have a limit, or the limit is infinity, then the series is divergent. divergesIf a series does not have a limit, or the limit is infinity, then the series diverges. seriesA series is the sum of the terms of a sequence.

When can the integral test be used?

The integral test helps us determine a series convergence by comparing it to an improper integral, which is something we already know how to find.

When can you not use integral test?

It is important to note before leaving this section that in order to use the Integral Test the series terms MUST eventually be decreasing and positive. If they are not then the test doesn’t work. Also remember that the test only determines the convergence of a series and does NOT give the value of the series.
