One Small Powerful Action
People often follow a certain path that has already been built, that has been chosen by many; they enjoy the comfort from having a certain outcome, the certainty from not having a risk. However, this attitude can foster apathy towards issues in our society. In order to make changes, Allison Howard, through A South African […]
Blog Log #2: Unique or Deformed
An article revealing a heartbreaking truth about man’s best friend took my attention as I browsing on Big Think. I have always been a dog-lover, which is a reason why I was drawn to this content. The writer, Jana Roose, establishes that flat-faced dog breeds such as pugs and boxers suffer painfully because of their […]
Blog Log #1: A Mean to Measure Citizen’s Value
I recently came across a mind-blowing article – Leave no dark corner – written by Matthew Carney on ABC News. The article conveys China’s social credit system, which is planned to be implemented by 2020. The scoring system involves the combination of the latest high-tech surveillance system and a massive amount of data collected from […]
Week 18: Top 5 Things I’ve Learnt in Pre-Calculus 11
Graphing Inequalities and System: After learning about these graphs separately, I notice that these two can be combined to make a system with two inequalities. By graphing, you can quickly tell the solutions by looking at the graph. Ex: and We can graph out this system on the xy-plane: The overlaping part indicates the solutions […]
Week 17: The Sine Law and The Cosine Law
This week, trigonometry will be upgraded. The Sine Law and The Cosine Law are the general formulas that work based on the relationship between the sides and angles in triangles. If primary trigonometric ratios can only be applied to the right triangles, these Laws can be used for any triangles. * The Sine Law: […]
Week 16: Application of Rational Equations
Rational equations can be used to model real-life situations, which allow us to find the missing information, in other words, to solve for the variables. From the given problem, there are general steps which help to break down the information and construct the correlative equation: Read the problem and identify what is being asked. Introduce […]
Week 15: Adding and Subtracting Rational Expressions
* In adding and subtracting rational expressions, whether with monomial or polynomial denominators, there are general steps to follow: Identifying the non-permissible value(s) Determine the lowest common denominator (LCD) by factoring the denominators. Rewrite each fraction as a single equivalent fraction with the LCD; be careful with the negative sign when multiplying the numerators by […]
Week 14: Multiplying and Dividing Rational Expressions
The strategies for multiplying and dividing rational numbers can be used to multiply and divide rational expressions. *Multiplying: Identify the non-permissible value(s) of each expression, the value of x that makes the denominator(s) equal to 0. Divide the numerators and denominators by their common factors Multiply the numerators; multiply the denominators. Example: The non-permissible values […]
Week 13: Graphing Reciprocals of Linear and Quadratic Functions
Reciprocal is the quantity obtained by dividing 1 by a given quantity other than 0. The reciprocal of f(x),, is . The graphing of the reciprocals is a hyperbola. *In order to graph the reciprocal of a function, we need to find some information: – Asymptote: the invisible line that the hyperbola slowly reaches without […]
