Waching daily Jul 3 2018

Yesterday saw the announcement of the Banned and Restricted Update, and while "No changes

to any formats" is the easy pick most updates, that wasn't the case this time.

Both Deathrite Shaman and Gitaxian Probe were banned in Legacy with just under five weeks

until the multi format Pro Tour 25th anniversary.

Ian Duke posted the update going over the changes.

Deathrite Shaman appeared not only in the most popular decks, but those decks were also

posting high win rates over time.

Gitaxian Probe, on the other hand, was less prominent in the top decks, but did have several

issues, including the alternative phyrexian mana cost making it free, allowing more information

about what your opponent has, and adding to graveyard and storm style decks.

There was also a section on why Goblin Chainwhirler will still be in Standard, despite the early

success of the card and the calls for it to be banned.

MTG Arena recently added Kaladesh and Aether Revolt to the game to complete the current

Standard format, and Core Set 2019 is ready to launch with a few new updates.

Chris Clay and Nate Price hosted a video that was posted yesterday, talking about all of

the changes that will be coming up in mid-July.

The New Player Experience will add five tutorials to the game, which experienced players can

skip after the first one.

New language options are also being added, with French, Italian, German, Spanish, and

Portuguese.

Players will also now be able to pay through PayPal, and support for Euros is being added

as well.

One of the biggest changes, though, is probably the change to Wildcard tracking.

Now, instead of every pack that is opened being added to the Vault, that progress will

go towards the Wildcard track, which will provide a Wildcard between Uncommon and Mythic

after three packs have been opened.

The Vault will still fill as players open the fifth or higher copies of cards, as it

did previously.

In the newest video essay on Rhystic Studies, Sam shows us his fondness for creepy, crawly

critters.

Sam goes over not only the history of the card Giant Spider, but also the history of

giant spiders in popular culture throughout the years, including Lord of the Rings, Harry

Potter, and Director Kyle's favorite film, Wild Wild West.

Sam also provides some insight on how Magic artists have depicted spiders in the game,

from artwork depicting regular spider species, to the more stylized fantasy based versions.

The Magic Bracket is finishing up the round of 256, and there are still a few batches

open for players to vote on.

Now that the bracket has been pared down this low, we're seeing matchups between some

truly iconic cards.

Bird of Paradise vs Damnation, Brainstorm vs Hymn to Tourach, Llanowar Elves vs Delver

of Secrets, and Young Pyromancer vs Doubling Season just to name a few.

After these last few batches finish, there will be a short break, and then the Top 128

cards will paired and voting will open on July 23rd.

A new video series, Flashback, kicks off today on StarCityGames.com's Premium side.

The show has Magic personalities travel down memory lane, as they are shown pictures from

throughout their life, mainly of their Magic accomplishments, and they tell their stories

surrounding those times.

The first episode kicks off with Todd Anderson, going through some of his Magic experiences,

including his first Grand Prix Top 8, his StarCityGames.com Invitational win, and his

love of Dungrove Elder.

That's our show for today, July 3rd.

and strategy.

4.2 - Video 2 - Special Coordinates on the Unit Circle - Duration: 3:53.

Recall that the unit circle is one of the ways that we can compute the values of trigonometric

functions.

If we draw the unit circle and draw an angle in standard position, the coordinates of the

point where the terminal side intersects the unit circle gives us the values of the functions

according to this chart.

On the unit circle, there are some important coordinates at certain angles that you must

know.

In a later video we will derive the values of this using the Pythagorean theorem, but

for now we will simply learn them heuristically.

We begin with the angles built around increments of pi/2 or 90 degrees.

As we work our way around the circle, we get the angles of 0, pi/2, pi, 3 pi/2, and 2 pi,

which is coterminal with 0.

The coordinates of these angles are easy to remember because they all lie on the coordinate

axes.

All you need to remember is that the unit circle has radius 1 and this will tell you

exactly what the coordinates are for each of these angles.

We will next look at the angles built around increments of pi/4 or 45 degrees.

In addition to the previous 4 angles we also get pi/4, 3 pi/4, 5 pi/4, and 7 pi/4.

All of the new coordinates will be a plus or minus sqrt(2)/2.

The signs of these coordinates will correspond to the quadrant.

In the first quadrant, both coordinates are positive.

In the second quadrant, the x coordinate is negative and the y coordinate is positive.

In the third quadrant, both coordinates are negative.

And in the fourth quadrant, the x coordinate is positive and the y coordinate is negative.

Lastly, we will look at the angles built around increments of pi/6 or 30 degrees.

In addition to the angles we already have, we will also get pi/6, pi/3, 2pi/3, 5 pi/6,

7 pi/6, 4 pi/3, 5 pi/3, and 11 pi/6.

Each of these new coordinates will either be a plus or minus 1/2 or plus or minus sqrt(3)/2.

You will be able to identify the proper signs by looking at the quadrant, but you also need

to use some logic to figure out which is which.

The important fact to remember is that the sqrt(3)/2 is greater than 1/2, so that

when you look at the picture you will be able to jus choose the coordinates that correspond

to this fact.

For example, at pi/6 the x-coordinate is greater than the y-coordinate, so the x-coordinate

gets sqrt(3)/2 and the y-coordinate gets 1/2.

At pi/3, the y-coordinate is now larger, so that one is sqrt(3)/2, which makes the x-coordinate

1/2.

This pattern continues all the way around the circle.

This looks like a lot of information, and it is, but by thinking this through and paying

attention to the signs and with a little bit of practice you can work your way around the

entire unit circle and get all of these values.

The points in the first quadrant are very important to this course.

Recall that the coordinates are related to the sine and cosine functions.

You are expected to memorize these and be able to reproduce them on command.

Fortunately, it takes just a little bit of practice to get these values to stick.

Notice how sine starts at 0 and the numerators count up.

Cosine uses the same values but in the opposite order.

This will help you keep all the numbers straight.

You can also look up the sine and cosine finger trick if you're still having problems.

As a side note, sqrt(2)/2 is approximately 0.707 and sqrt(3)/2 is approximately 0.866.

These are useful values to know, but it's more important that you know the exact values

and not the numerical approximations.

In the next video we will look more closely at these values and make a further observation

about our trigonometric functions based on the unit circle.
