This week we learned the calculations that involve radicals such as add, subtract. In the case of add and subtract we need to convert the subjects that we are adding into mixed radicals with the same radican. EX: $\sqrt{12}+\sqrt{27},2\sqrt{3}+3\sqrt{3},5\sqrt{3}$ when the radicals have the same radican you will have to add the exponent of the mixed radical and keep the radican the same. For multiplication and division you can just apply the rules of multiplication and division on entire radicals with one exception, that is you can’t write denominator as a radical.

## Week 3- Absolute Value

In this week’s classes, we learned the concept of absolute value…

Absolute value expresses the distance between numbers on a number line, due to the fact that there can’t be a negative distance as it is a scalar value, everything coming out of the “||” are positive. and the expression within absolute value get prioritization in an equation, such as

3×2+|2-3|, 6+1=7.

## Sum of Infinite Geometric Series

In this week’s Math 11 Pre-Cal I learned that you can actually determine the exact Sum of Infinite Geometric Series in certain situations, when they are converges.( when -1<r<1) as with a rate less than 1 and greater than -1 the next term will get closer and closer to zero, therefore there is a determinable  sum. In the case of a diverging series, the  sum will get infinity big and therefor we can’t determine the exact sum.

The equation for the sum of an regular Geometric Series is

Sn=$\frac{a(1-r^n)}{1-r}$

When -1<r<1 $r^n$ approaches 0 as n increases indefinitely.

So, Sn approaches Sn= $\frac{a(1-0)}{1-r}$, therefor $S\infty= \frac{a}{1-r}$

EX:

A Infinite Geometric Series where r=0.5

8,4,2,1

$S\infty= \frac{8}{1-0.5}$ $S\infty= \frac{8}{0.5}$ $S\infty= {16}$

## Week 1 – My Arithmetic Sequence

My Arithmetic Sequence:

21,23,25,27,29

The Sequence has a common difference of +2

Part one:

Tn=T1+(n-1)D

T50=21+(50-1)2

T50=21+49×2

T50=21+98

T50=119

Part two:

Sn=(T1+Tn) $\frac{n}{2}$

S50=(21+119) $\frac{50}{2}$

S50=140$\frac{50}{2}$

S50=140×25

S50=3500

## “Top of the World” English 11 Narrative Essay

Top of the World

-Jeremy Zhao

My feet hanging off the ledge, thousand feet of darkness lying beneath me; I feel like I’m really on top of the world.

It all started with a dream. Mountain biking has always been my passion. Although my hometown-shanghai, China is one of the biggest and most populated city on earth it is possible the most unlikely place for one to mountain bike, but I kept this hobby throughout my childhood.

Although there are a handful of trails a few hours’ drive from Shanghai, they are all poorly build, poorly marked and do not have any sort of challenge. But on the other side of the globe, it’s a completely different story…

The holy land and the founding place of mountain biking, British Columbia, Canada with more than 8000 marked trails and world’s best lifted accessed bike park -Whistler. Whistler has always been my dream destination for mountain biking, but it is halfway across the world.

Well, that’s not the case anymore. Now I live here, Coquitlam: five minutes’ drive from world class mountain bike trails and two hours drive from Whistler.

Whistler is such a majestic place, with the roaring rivers, the snow-capped mountains, it is truly the Garden of Eden for extreme sports and Heaven for sportsman alike, but one must admit the crown jewel of it all is the peak of Whistler. Sitting at 7000 feet, the peak chair of Whistler is one of the highest chairlift in BC. Although the peak zone is nothing of too much significance in winter, when the summer rolls around it becomes something special.  A trail like no other lies here, Top of the World: a trail covered with razor-sharp rocks and thousand feet clip to the side. Stretches over five kilometers and 2000 feet of elevation, a trail that’s limited to 100 riders daily, only open two months per year and a trail that cost extra 20 dollars per lap: this is not an easy trail to ride.

Even within so many restrictions, one must try this trail. And that’s exactly what I decide to do in the summer of 2016.

I sprint out of the bed; today is the day; I am going to ride Top of the World. But there is a catch… Anyone with common sense will ride whistler bike park with full face helmet and neck brace, unfortunately I broke my helmet the day before riding Top of the World. After debating with myself all night I decide YOLO and kept my plan of riding a few of the hardest trails with a half face trail helmet, I’m sure I was one of the handful maniacs who did that in 2016.

I walked into the bike park, my heart is pumping so hard, I’m not only riding one of the hardest and longest trail on the mountain that I have never ridden before, I’m also doing it without adequate protections, If I mess up and crash I will plow my face straight into those razor sharp rocks…

As those scary thoughts rushing through my mind, as time flew past. When I came out of my thoughts I was already at the roundhouse and about to load up the peak chair… On to the peak chair we go, I look down, the view is so different than winter. Without the soft puffy snow covering everything, the mountain doesn’t seem so kind with it’s scattered sharp rocks and hanging cliffs…

After a short ride, I’m at the peak of Whistler, it was a long journey but I made it… My feet hanging off the ledge, thousand feet of darkness lying beneath me. I felt like I’m really on top of the world. This is what I live for.

The ride was amazing and I didn’t plow my face into the ground as I thought I would…

## Is it appropriate to use First Nation names or mascots as sports team name?

Is it appropriate to use First Nation names or mascots as sports team name?

After the extensive research of in regards of whether it’s appropriate to use Native American names and mascots as a professional sports team name or mascot, I am somewhat torn…

In this Inquiry my personal area was the naming controversy of the Washington Redskins, arguably the most publicized and controversial team name in recent history. My personal opinion on this topic before the research was, First Nation mascot and names are appropriate to be used as long as it was portrayed correctly. And my opinion remains the same.

Most Native American team name was not designed with the intent of being used as a racial slur, instead often it’s used to honor native induvial who had great contribution with the team. In the case of the Washington Redskin, according to a letter from the team owner Daniel Snyder, the team was renamed to “Boston Redskins” from “Boston Braves” in 1933 to honor the four Native American players on the team at the time and the legendary head coach at the time Lone Star Dietz (William Henry Dietz, Sioux Indian) who is also native (There are controversy with if he is really a Native American).

But if they did not portray the Native American image correctly than that’s inappropriate. In the case of the Washington Redskins, although the intention of the naming was good but the origin of the word Redskins was very cruel- the word redskin came from the time when European settlers will kill Native Americans for bounty and then they referred the natives as the Redskins. So in the case of the redskin, when whoever named the team 84 years ago was poorly educated and they should recognize the issue and change the name.

Personally, like I previously stated, I believe it’s ok to use First Nation mascot and names as long as it’s accurate. Even the ad campaign by National Congress of American Indians against the Redskin name was about calling them self the correct terms, I don’t think anyone would mind if a team is called Chicago Lakota.

## “Dead Poet’s Society” Reflection and Connection

1. In the Movie “Dead Poet’s Society” the boys lost hope for their life because they can not pursue their dreams and passions, and Neil Perry end up killing him self because his parents forced him to be a doctor does not listen to his opinion at all… Just like the soliloquies From Macbeth “Tomorrow, and tomorrow, and tomorrow.” In that soliloquies Macbeth just lost his wife and the prophecy of the witches has come true and he know the end is near for him and the soliloquies express how Macbeth think life is meaningless just like how boys think their life is in the movie.

2. From the Movie ” Dead Poet’s Society” I learned you should always voice your opinion and pursue your dreams, you live for your self not others you should take control of your life. In the Movie the boys future were completely planned out by their parents and their own opinions does not matter, they lost hope in their life because their passion and voice were taken away from them and they thought their life were meaningless…
