Praise Song for the Day
“Doing their tasks and accepting the fact that they had to do things that they wanted to do, and they are clinging to the idea that hope is coming in the future. The hope is that Obama will help build that bridge to a better future.”
Praise Song for the Day by Elizabeth Alexander, is an ode about Barack Obama’s Presidential inauguration. This ode stresses the hope Obama has brought to citizens around the nation. “I know there’s something better down the road. We need to find a place that is safe.” (Line 22-23) refers to the Americans, (Immigrants) who left their homelands, in search for a better life for their family. “Praise song for the struggle, praise song for the day” (line 31) This line correlates to African slavery age and people who died for this day (inauguration.) Finally, Elizabeth Alexander wraps up the poem “praise song for walking forward in that light.” (Line 43) making reference to the theme of the poem, Obama’s inauguration. This closing line shows that there is hope for America.

A World Without Technology: A World Without Growth
Many people may view technology negatively, especially older generations who are not quite as informed on the benefits and its proper use. A lot of people think of technology for its shallow purpose of social media. It may be falsely viewed it as a distraction but this is simply the product of misuse. When used correctly, technology can improve all fields of work, research, communication and even making our day to day lives easier. Technology can be used as a tool to improve knowledge, access to deeper connections and resources. Although overlooked, when we think about the effect it has on our day to day lives, a world without technology would be a much less effective, sufficient world. Many people say technology is causing more harm than good. They say problems such as bullying, global warming and addiction are a result of technology. Although misuse can cause these problems, technology can be used to improve and fix these problems. Bullying exist everywhere, online and in person but, many advertisements and posts online are used to spread anti-bullying messages. Inventions such as solar power and electric cars are made in an effort to save the environment. When used correctly, social media can be a tool for communication and connections.
Newtons Laws
Newtons Law #1
Newton’s first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is represented in how the bottle on the roof moves with the car until the car stops, this in turn, changes the bottle’s state but continues to move it forward.

Newtons Law #2
The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass over velocity) per change in time. This is represented in how we push the car to move it forward, subjecting an external force to change the velocity.

Newtons Law #3
The third law states that for every action (force) in nature there is an equal and opposite reaction. More explained if object A exerts a force on object B, object B will exert the same force back to object A. This is represented in the video by how the wheels of the car when accelerated push against the ground, force is put into the earth and at the same time is pushed back into the car; however, because of the difference in size between earth and the car, earth becomes unaffected by the force while the car is sent forward leading to acceleration.

Week 18- 5 Things I Learned in Pre Calculus 11
1. Factoring: Knowing how to factor was the most important thing to know in this course. Coming from Pre Calculus 10, I didn’t really remember how to properly factor. I can say now that it is engrained in my brain after using it in almost every unit this semester. Especially as the equations were only going to become increasingly harder, we constantly reviewed and went over factoring.
Example: 
2. Sine Law: Learning the Sine Law made things much easier for me. The Sine Law is a formula/law that basically allows you to find any angle/side in the triangle as long as you know a matching side+angle, and the opposite side/angle to the one you are trying to find. Making sine law a very useful tool when it comes to trigonometry. Angle A/B/C and side a/b/c are opposite to each other.
3. Completing the square: Due to the course of PreCalc 11 having lots of graphing and quadratics, you are going to need to know how to solve in the semi-frequent situation of when you cannot factor the equation. In this case you complete the square. Completing the square is when you take the middle term in the quadratic (also known as the “b” term), divide it by 2 and then square it. Then you take the original last team (or “c” term) and move it outside of the original quadratic, and solve to find the zeros of the equation.

Week 17
This week we learnt about the Sine Law. The Sine Law is basically a formula that you can use to find a missing side/angle if you know a matching angle+side and the opposing angle/side to which you are trying to find.
The formula:
Using the formula itself is pretty simple, you input the known information. Then remove the one of the a/b/c you do not have enough information to use, and solve for what you are looking for.
Week 16
- Since the denominators are all equivalent, the first step is to combine and simplify the numerators by combining all like terms.
- You can then simplify further by eliminating x-3
- This will leave you with 1/x+3
Week 15-Addition and Subtraction of Rational Expressions
Simplify: 1/3a+2a/5a
The first step to adding these together is to find the common denominator of 3 and 5. This will be 15. You will have to multiply 1 and 3 by 5 and 2a and 5a by 3. This will result in 5/15a + 6a+15a=11/15a
