What I Learned This Week
September 12, 2014Posted by on
I was looking for graphing software for my iPad that handled aysmptotes better than any of the other calculators I have installed. I found an app called Desmos. After experimenting on my iPad I found that Desmos could also be run right from their website. And better yet, you could save documents right to your Google Drive so that they could be opened anywhere.
THE GOOD: Desmos allows multiple graphs. You can toggle graphs on and off. You can add a table that is in the equivalent of Texas Instruments ask mode. If you are projecting the graph a setting increases graph thickness and font width. It automatically finds maximums, minimums and intersects. Zooming is easy using the wheel on a mouse or pinching on the app. The app and the website are free and ad free.
WHAT’S MISSING: Intersection features are hard to use or missing [EDIT - NOPE FOUND THEM]. You can draw dashed lines, but I couldn’t find a way to graph inequalities [EDIT - JUST TYPE ]. I did not try to graph any implicitly defined equations, but I don’t think it has this feature [EDIT - IT DOES].
All in all this is good presentation software and it is easy to share the graphs using links generated by the software. For most of my algebra lessons I would use this in place of the TI-84 if I were just presenting or the students had access to computers or smart phones. For interactive lessons the TI-84 still has a place because of the technology available to students.
EDIT: AND EASY PARAMETERS AND POLAR COORDINATES AND … THIS IS GREAT!

The Tigers seem to be doing better with me doing school work and wasting time on the internet based on quick checks of my Twitter feed. So, I will catch up on recently sampled beers.
Oatmeal red ale sounded very interesting. My first impression was actually favorable as I liked the strong hoppy flavor. Later some of the sips had an almost medicinal aftertaste. This is one I don’t think I will get again.

I wasn’t going to blog about this beer since it isn’t great. But, the Tigers were down 4-0, I had already done 45 minutes of work and I was looking for a way to procrastinate. Writing beer reviews mostly for yourself on the internet is a great way to procrastinate.
I had wanted to try this beer for some time (well since I thought I could get it cheap before 7 at the bar in Fleming’s only to find they had switched to Summer Shandy) and a local store lets you mix and match a six pack for $8.99. So I bought and tried one. This beer is citrusy and safe. It is nothing particularly special, but it would make a good compromise beer if your family wants to drink Summer Shandy and you want to drink Two Hearted Ale. Since Sam Adams is ubiquitous at chain restaurants it would also make a good alternative to domestic pilsners.

We went to see the Hernandez v Price match up yesterday. We bought standing room tickets since the secondary market was high for real seats. The Tigers won 4-2. Price pitched 8 innings. He only allowed 1 run and got out of a bases loaded jam in the 8th. Hernandez left after 5 innings. He was only at around 90 pitches, but in the 4th he was hit by a sharply hit ground ball.
Standing by the Kaline statue you meet some interesting folks. Several people wanted to take selfies or panoramic shots. I tried to accommodate those who asked between innings. Those who asked during action got the same look I typically give those doing the wave.
One fan spent half an inning describing which pitchers she found attractive. She was a bit more graphic. Her boyfriend took this all in stride.
We left before the fireworks since we saw them at Friday’s game. I’ll pretend I can’t remember Friday’s game. We also wanted to beat the One Direction fans at Ford Field to I-75.

A Tigers Twitter friend posted a picture of a six pack of Bell’s Mars he procured from a local wine shop. Mars is the first of 7 specialty brews from a planet series. I thought I might try my luck to see if the shop had any unencumbered bottles. It ended up win-win-win. I got two bottles. The cost was obnoxious. I didn’t have to specifically name drop the other person- I just vaguely referred to Twitter.
Now since this is the first post in my beer series you should know that I prefer dark beers, or nutty brown beers. The exception to this is Bell’s Two Hearted Ale, an IPA. Bell’s Two Hearted Ale is the beer to which all beers are to be compared.
Mars does well even when compared to Two Hearted Ale. It starts out citrusy, then it tastes a bit bitter. The malt gives it a great body. It almost finishes sweet or with umami.
It is a shame this beer is only available in a limited batch. It’s great.

I just want to upload the image full-size to link to Twitter. Click to enlarge.

Here are the updated results by pitcher. It seems to pass the “eye test.” Smyly and Sanchez have worse records than the other regular starters, but they show up a lot on the one and two run losses. Sanchez seems to be the best pitcher to me despite the Tigers having a 5-6 record in his starts. All the Tigers are getting between 4 and 5 runs of support per start except for Smyly who is only getting 3.36 (ESPN).

During our recent trip to the San Francisco Bay Area we also went to Oakland to see the Tigers play. We had 4 tickets, but my oldest daughter could not make it so I used Twitter and 3 connections to give away the last ticket to Chris the A’s fan. Chris was good company and from Chris I learned that part of the stadium in the outfield that had changed the most from the late 80’s was called Mt. Davis in “honor” of the owner of the Raiders who got the boxes installed as part of a package to return the Raiders from LA.
We took the train- Bart this time- from near out hotel in Millbrae. It takes a long time to get to Oakland from there, but I really don’t like parking at away games and the BART platform is connected to the O.CO Coliseum area by a pedestrian overpass.
It was hat day in Oakland, too. Oakland is still getting used to the metal detectors it seems as it took 20 minutes to get in the stadium. The metal detector lines were all held at one point to allow a back up at the ticket scanning area to clear as well.
Concession lines were ridiculously long. Some people said that this is because many vendors and other support workers work for both the Giants and the A’s who are rarely scheduled at home on the same weekend. Normally lines are not as bad and you can find vendors in the stands. At this game the few vendors were able to stay in a mid-level path in the 100 sections and have fans come to them! I did find a good barbecue place in the outfield. It was nowhere near as good as the KC barbecue place, but it was better than typical ballpark fare.
We had seats near the Tigers bullpen. The seats were good. I won’t speak of the game except to note that it didn’t worry me that Coke was warming in the late innings. It also didn’t worry me that he gave up a single before an error by the shortstop and a catcher’s interference. It also didn’t worry me that he gave up a grand slam- the fifth homer against the Tigers that day. This got us to the train platform before the real rush of fans came.

This Saturday we visited San Francisco to see the Giants play. We were visiting my daughter who lives in Palo Alto now so we took Caltrain to the stadium. It was great. It cost $14 round trip. It dropped off about 2 blocks from the stadium. There was a Safeway on the block between the station and AT&T Park where we bought water. An express train skipped the first few stations on the way back and got us quickly back to Palo Alto. My youngest daughter was also excited to be on the upper deck of a two-level train.
It was hat day which led to long lines to get in the park. But, once the gates opened we were in the park within about 10 minutes despite being wrapped 2/3 the way along the walkway between the stadium and the water in right field.
My daughter had Twin gear from a previous trip. She was not able to score a ball or autograph before the game. We did see Eduardo Escobar give a ball to a reluctant 2-year-old. He set the ball on the pad over the railing. When she did not grab the ball he gently pealed her fingers off the rail and wrapped them around the ball.
Overall I thought the park was nice. I don’t think I’d rate it as highly as others. I found the concourses too narrow to navigate easily when crowded. The view was great, but not as good as Pittsburgh.
The weather was typical late spring in San Francisco. It was warm until it became bitterly cold because of the wind.
The vendors had some fun things though. Cotton candy had 4 colors. Hot chocolate vendors carried huge containers on their backs from which to dispense drinks.
Most importantly the Twins lost!
