= diverges Since the integral diverges, then the series also diverges. 17.(4 points) Use the comparison test to determine whether the series ¥ å k=1 lnk k converges or diverges. Solution: For k > 3, lnk > 1, so lnk k > 1 k. å 1 k is the harmonic series and diverges, so by the Comparison Test, å lnk k diverges. 18.A function f is deﬁned by ...
Ayman's proof shows the original improper integral is not absolutely convergent. But, working without absolute values, we can show that the series is conditionally convergent. Work with the integral on [2 pi, \infty), and break up the integral into regions where the integrand is positive and negative.
▸ Neural Networks: Learning : You are training a three layer neural network and would like to use backpropagation to compute the gradient of the cost function. In the backpropagation algorithm, one of the steps is to update for every i,j. Which of the following is a correct vectorization of this step?
In this example theres three conditions before we can use the integral test, it needs to be continuous, positive decreasing function. I plugged in the series in my graphing calculator, it's continuous, positive, but not decreasing from n=1 to infinity. It stays at zero for n>= 16. So Instead, I used the Ratio Test...
Use alternating series test to determine whether the series converges or not View the step-by-step solution to: Question
Normally when an optimization algorithm does not converge, it is usually because the problem is not well-conditioned, perhaps due to a poor scaling of the decision variables. There are a few things you can try.
Another well-known convergent infinite series is Brun's constant.. A number of methods known as convergence tests can be used to determine whether a given series converges. . Although terms of a series can have either sign, convergence properties can often be computed in the "worst case" of all terms being positive, and then applied to the particular series at ha

The definite integral of a function is closely related to the antiderivative and indefinite integral of a function. The primary difference is that the indefinite integral, if it exists, is a real number value, while the latter two represent an infinite number of functions that differ only by a constant.
