http://www.arfmagazine.com/cgi-local/arfblog.pl?viewcomments=kiddexterity=200501=1106258878
After class yesterday morning (finding the area between two curves through integration — more on that later), it became readily apparent to me that I should go to the Trig Review class yesterday evening for a brush-up on identities and other fundamentals. I think I am pretty solid on the basics:The Pythagorean Theorem: a2 + b2 = c2. If you know two sides of a right triangle, you can find the third. Grade school stuff.Sine θ = Opposite/Hypotenuse, Cosine θ = Adjacent/Hypotenuse, Tangent θ = Opposite/Adjacent — in other words, the SOHCAHTOA nonsense.Reciprocal values of Sinθ, Cosθ, Tanθ: 1/Sinθ (Cosecant), 1/Cosθ (Secant), 1/Tanθ (Cotangent)Inverse values of Sinθ, Cosθ, Tanθ: Sin-1θ (Arcsin), Cos-1θ (Arccos), Tan-1θ (Arctan)The 30°-60°-90° and 45°-45°-90° trianglesThe Unit CircleWhat I'm not so hot on:Identities — Half-Angle, Double-Angle, Sum & Difference, etc. The hardest part is knowing why they are true. I get that Cos2θ + Sin2θ = 1 (as it relates to the Pythagorean Theorem and the area of a circle [x2 + y2 = r2]), and from that we can derive the identities of Sec2θ = 1 + Tan2θ and Csc2θ + Cot2θ = 1. What I don't get is why Sin2θ = 2Cosθ * Sinθ. Could somebody show me a proof that won't confuse me further?Law of Sines and Law of Cosinesand much, much more!There's another Trig Review next Wednesday night which I'll probably attend. Tonight's homework is the aforementioned area between curves, which hopefully I can do if I don't wind up staying too late at my second job tonight. Either way, expect more hot MathBlog action in the near future!http://www.arfmagazine.com/cgi-local/arfblog.pl?viewcomments=kiddexterity=200501=1106166096Wed, 19 Jan 2005 15:21:36 EDTGoodbye, subscribers.

All right blogfans, after a minimal amount of deliberation I think I have some new thematic material for my blog, but I don't think it's going to interest anyone. In fact, it doesn't even interest me, so I'll completely understand if y'all want to unsubscribe to this blog as soon as your browser will let you.Given that a)my time is extremely limited, b)I need to use said time as wisely as possible, c)I need to study for my math class in addition to working, and d)I don't really like studying for my math class in addition to working, I've come up with this idea: why not blog about class? That way, it's like studying, only lamer!So, thank you to all my lovely subscribers, and I wish you well in your blog searching. Coming next: MathBlog!http://www.arfmagazine.com/cgi-local/arfblog.pl?viewcomments=kiddexterity=200501=1105718412Fri, 14 Jan 2005 11:00:12 EDTI Assure Your Quality

I found another bug when my Loverboy joke backfired - underscores embedded in HTML get turned into hyphens. Also, HREFs in post previews are still wonky.Tanner, you owe me a Coke Slurpee!http://www.arfmagazine.com/cgi-local/arfblog.pl?viewcomments=kiddexterity=200501=1105481427Tue, 11 Jan 2005 17:10:27 EDTThe Blog Stops Here
http://www.arfmagazine.com/cgi-local/arfblog.pl?viewcomments=kiddexterity=200501=1105481427
The "Recent Comments" code done blowed up, but square-jawed Tanner fixed it pronto. I feel as though should have thought to test that, but I didn't think of it. Alas.So that's about it. Blog gamma-testing is winding down. Things are pretty much a "go," or "green-light," or "ready for prime time," or whatever colloquial synonym you prefer. The time has come to ask, To blog, or not to blog? That is the question. What say you, ARFers? I'll consider any suggestions in the comments.http://www.arfmagazine.com/cgi-local/arfblog.pl?viewcomments=kiddexterity=200501=1105120068Fri, 07 Jan 2005 12:47:48 EDTSame Ol' Schtick
http://www.arfmagazine.com/cgi-local/arfblog.pl?viewcomments=kiddexterity=200501=1105120068
Yet another blog entry to test more of Tanner's blog features. Gotta keep at it to find those bugs. Gotta keep pushing the envelope. Gotta keep stretching the boundaries. Gotta break 4:40.I will need a new schtick soon for my blog, if I'm to keep blogging at all. Tanner's got the whole "I wrote this whole thing and you must respect me!" thing. The Normal has the "My very existence is the central rotational axis of this website as exemplified by the fact of my blog appearing on the front page" angle. Jayrock seems to be taking the "I'll flatter my blog with platitudinous sincerity" route. And I can appreciate all of those, truly. But once gamma-testing is over, what's to be my unique, blogarific signature? I mean, I don't even have any cats I could write about.Updated: 01/07/2005 at 1:02 pm by kid dexterityhttp://www.arfmagazine.com/cgi-local/arfblog.pl?viewcomments=kiddexterity=200501=1105043914Thu, 06 Jan 2005 15:38:34 EDTSubscribe This!

Here's a blog entry so Tanner can test e-mail updates... and the rest of you lucky subscribers can too!I'm going to need to come up with a new blogging angle once the gamma-testing is over.Updated: 01/07/2005 at 7:11 am by kid dexterityhttp://www.arfmagazine.com/cgi-local/arfblog.pl?viewcomments=kiddexterity=200501=1104944675Wed, 05 Jan 2005 12:04:35 EDTI Can't Get Behind That!

I have never blogged before. There are a few reasons as to why. First, I don't frequently feel the need to advertise. Second, I figure I spend enough time on introspect, to then convert my introspect into outrospect seems redundant and tiring. Third, I really loathe the word "blog." It just sits there in the bottom of your mouth, like the loogie you were going to let loose before the teacher started watching you.But, Tanner went to all this trouble to go blog-tastic, and I feel it is my duty as friend and troublemaker to gamma-test the shizzle out of his software, so I'll blog for a while. Who knows, maybe I'll grow to like it. After all, Mr. Darcy didn't think Jane would like French apples, but she did!
