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 4- Adding Radical

This week, I have learned how to add radicals. At first, I thought it would be hard because adding fraction is harder than multiplying fraction. However, it was very easy. It has the same concept as fraction. Let’s try an example. +  For fraction, you leave the denominator and add the top, for radicals, you add the coefficient and leave the radicand alone. So it should look something like this…

Week 1 – My Arithmetic Sequence

Part 1 This week, I have learned how to solve arithmetic sequence and series. Before we begin, we must learn some vocabulary to be able to solve these questions. Arithmetic sequence: is a sequence of number that the difference between the consecutive terms is constant. Ex: The sequence 1 ,3, 5, 7, 9, …  is an arithmetic progression with common difference of 2. General term: To determine an expression for the…

Lesson 5: Multiplying Polynomial

This week, I have learned how to multiply polynomial. I have learned different methods, however, this is the easiest way to solve.  When you follow step by step, you will gradually understand the rules and the steps to reach the answer. Before we start the calculation, we must learn some vocabularies. Variable: A letter that represents one or more numbers. Algebraic Expressions: Expressions like 2a-b+4. Monomial: A number or a…
