# Desmos Art Functions Card 2018

https://www.desmos.com/calculator/ckhofitzny  During this desmos project, there were several problems and difficulties where I took several hours to find a solution. I had to go on YouTube for examples to create functions and it took me several hours and days to finish this project. One of the most common problem was making each lines were connected to each other. On desmos, it will show you a white dot that explain the…

# Week 18- Final

My top 5 in Pre-cal 11 Arithmetic sequence and series I  enjoyed how I learned there are many other different ways to find the total of an amount or find the next amount of the sequence. Trigonometry In this unit, I enjoyed how I expand the learning of SOH CAH TOA. Using Sin law, or Cos law made me think whether to use one of them. Absolute Value Using the…

# Week 12 – Graphing absolute value

This week, I have learned how to graph absolute values. The difference between last week and this unit, There is a lumps everywhere.   On the graph, you can see there is a lump in the middle. This is because of absolute value. when you add absolute value signs, the answer can’t be negative. As a result, there is a lump in the middle which is the new vertex. This also…

# Week 9- Finding the x intercept (Zeros, Roots)

This week, I have learned how to find the x intercept from a quadratic formula. At the beginning, I was very surprised since the step it took was very simple and understandable. From y= to y= (x+2)(x+6), this was using factoring!!! Since to find x intercept needed factoring, it was very easy. Let’s begin. As I mentioned before, it is factoring. The equation, y=a(x-x1)(x-x2), x1 is your first x intercept…

# Week 6 – Quadratic Formula

This week, I have learn a new method to factor. Its called quadratic formula. It’s a very easy way to factor, and find the answer very easily. The first step is find what is A, B and C. For example, A would be 1 B would be -12 C would be 36   Next step will be using the formula If you plug in and fill in A, B, C,…

# Week 5- Factoring polynomial

This week, I have learned how to factor polynomial. For me, it was very easy because I use a little trick to factor polynomial. For example + 4x – 6 Since they have GCF of 2 this can simplified very easily. After first step it should look like 2( + 2x – 3) Next we will factor 1 1 = 1 -1 + 3 = 2 (x-1)(x+3)   The first…
