So, since i hardly ever ask questions..and always in need of knowledge. I'll ask many questions to hopefully be answered.
1. When do you know if a test fails you and you need to do something else.
2. What tests are "inconclusive"?
3. What does inconclusive mean?
4. What came first: the chicken or the egg?
5. How do you do series with trig functions..like cos(pi/x)..?
6. How do you do the word problem things?
For the most part, i understood this chapter..these six questions always confused me though.. and i think on the test today i began to become more worried about that than what i needed to be worried about!

4. I do believe the egg.
ReplyDelete2. Inconclusive is when a test doesnt work. the conditions are different for each test. You should consult your chart for that. When you get inconclusive, you need to go back, and try a different test to see if a series converges or diverges.
5. Everytime I get a trig function in a series and I want to find whether or not it converges or diverges, I do the integral test. It's just a lot easier in my opinion. What you'll do is integrate as normal. HOWEVER, when you have the limit as n goes to infinity of a trig function, just plug in infinity for x (so in the example, it would be cos(pi/inf). the inside would approach 0, and cos0=1..)so it'll approach a number most probably...
1. mal is completely wrong... it's the chicken. if God just put an egg on the Earth, there would be no one to sit on it for it to hatch. sorry mal, haha
ReplyDelete2.the wrod problems are really just longggggg questions that ask you to do the same thing as every other problem. you just need to carefully identify all the information given to you and specify what is what, then work it out like normal.
Inconclusive simply means the test does not work. You should just try another test.
ReplyDeleteFor example: When using the ratio and root test, if you get 1 for your final answer the test is inconclusive. That is the rule.
