Holy crap, I forgot about the quadratic formula. Thanks for the help.

Homework Statement Al and Bert are jogging side by side on a trail in the woods at a speed of 0.75 m/s. Suddenly, Al sees the end of the trail 35 m ahead and decides to speed up to reach it. He accelerates at constant rate of 50 m/(s^2) while Bert continues on at a constant speed. (a) How...

Yeah, I can definitely do that part, I just I had a little trouble looking for the one little section I had trouble with.

Oh, I definitely see it now! Thanks. (^o^)/

Power Series:(n^n)*(x^n) Homework Statement The only step I'm having problem with on this problem is when I take the Lim n→∞ of the problem. I want to know how to cancel the n^n on the denominator during one of the steps. Homework Equations ∞ Ʃ (n^n)*(x^n) n=1 The Attempt at a...

Oh, jeez! You're right! I made a dumb mistake and forgot to divide the 1 in (2n+1) by n^2. Oh, and thanks.

Homework Statement I'm this series to see if it's convergent or divergent. I tried the root test, but it came out inclusive, and now I am trying to figure out if the ration test works. The only thing I'm asking which would be the right test for this. Homework Equations ∞Ʃn=1...

Alright guys. Thanks for the tip. I think get it now.

Oh. It seems that I have been doing this the wrong way since I haven't been introduced to Ci before. I'll make sure to double check my steps this time.

Homework Statement The question in the book is: "Use the sum of the first 10 terms to approximate the sum of the series. Estimate the error. My problem is estimating the error I'm looking for. I just need help with finding the integral. Homework Equations ((sin n)^2)/(n^3) The...

Homework Statement Determine whether the series converges or diverges. What I would like is some type of information on how to continue the problem. Homework Equations ∞ Ʃ √(n+1)/2n^2+n+1 n=1 The Attempt at a Solution I was thinking of doing a comparison test by doing...

I just figured that out, too. Thanks for confirming my answer though.

Homework Statement Find all points of intersection of the given curve. Homework Equations r = 1 - cos θ, r = 1 + sin θ The Attempt at a Solution 1 - cos θ = 1 + sin θ 1 = 1 + sin θ + cos θ 0 = sin θ + cos θ After that step, I blank out and can't think about how to get any...

I needed to find k in the equation.

Homework Statement This a problem that I didn't get completely right after a test, so I wouldn't mind figuring out what were my errors. A state game commission releases 40 elk into a game refuge. After 5 years, the elk population is 104. The commission believes that the environment can...
