This was taken in the reflection booklet #4.
And I realized something that helped me throughout all the other questions. I was looking at perpendicular all wrong and equations for that matter. It’s a step process
#1 perpendicular, you need to find slope
#2 you must accommodate the equation accordingly.
#3 understand that if your end result does not look like an equation. You might’ve done something wrong.

On this week, I learned what is perpendicular lines or parallel lines. When I have two slopes, if you take your slope and inverse it (-2 would become 2) it would eventually meet at 90*; thus making it perpendicular. However, if these two slopes are same, it would be parallel.
This is what I’ve learned in this unit. Not only how to calculate for the x y axis but also how to plot them onto a graph with the corresponding data.
Whenever you have perfect squares and a difference. You know their won’t have any middle piece to the polynomial. You will get conjugates. So you know you can multiply the two variables together and the units.
What I didn’t understand about this was you had to follow the “instructions” (the equation) like a book. You can’t skip a step nor rip a page out o the book you must read it. When it says there is 2 copies of the term then you must follow it and that you multiply it by 5 you must multiply the equation by 5.
1. Isolate the variables: move sin onto the other side of the equation and an index of -1
2. Place brackets around the opposite and hypotenuse
3. Solve equation with calculator
1. Isolate the variable: use cross multiplication
2. Re-write equation
3. Solve equation with calculator
1. Isolate the variable: multiplie 6 on each side
2. Re-write equation
3. Solve equation with calculator
What we did in class, we took different solutions and tested to see their reactions in different indicators, to differentiate if it’s an acid base or neutral.
Why did we did this, learning the indicators and their reaction rates with other solution is crucial in chemistry. Even if we didn’t know what the solution was we could find out by using indicators and learn if it’s an acid base or neutral in a safe way.
How this is used in the real world? Sulfuric acid, Acetic acid, Sodium Hyrdoxide are all acids and bases commonly found in the real world with real world applications. Ex/ Acetic acid is used in the manufacture of ink and dyes, of pesticides and food preservatives and of rubber and plastic.
