on The end is nigh! With the end of the semester so close, my last post will be explaining the sine law to the best of my ability. Basically what it’s saying is that the sin of angle A / side a is equal to the sin of the angle B / side b is equal… Continue Reading Week 18 – Pre-Calc 11
on Trigonometry! Or trig for short. Our minds have been blown this week with the idea that a triangle can go past 90 degrees! It is a little strange to conceptualize but the idea isn’t too wild. Let me explain. Our previous knowledge of trig ended with Pythagoras and that there were a total of 180… Continue Reading Week 17 – Pre-Calc 11
on Week 16! We’re getting close to the end of the semester, and that means finals. Putting that aside, right now we are learning about rational expressions and friends with some interesting results. This week’s big takeaway is the MASSIVE difference between an expression and an equation. This is always important, but especially in this unit… Continue Reading Week 16 – Pre-Calc 11
on Rational Expressions! A big word that really isn’t that bad. We’ve been doing simple rational expressions since grade 9, we just didn’t know it yet. Now, however, they are getting a bit more in-depth. All a rational expression is is an expression that has a polynomial in the numerator or the denominator. As I said,… Continue Reading Week 15 – Pre-Calc 11
on With the test on Thursday, this week was a difficult one. Most of it was studying and review, So that, is what I’ll focus on! What I mean by that is study habits and how to deal with an upcoming test. This is an extremely important skill in any course at any time in your… Continue Reading Week 14 – Pre-Calc 11
on Absolute value functions! Another type of function on the rapidly growing list of functions we are learning. However, the unique quality of these ones is the fact they contain an absolute value. If you go all the way back to Unit 1, you will find that we briefly covered absolute values. the rundown is that… Continue Reading Week 13 – Pre-Calc 11
on This was our last week before our Graphing Inequalities and Systems test. We were learning right up until the day before so there has still been a lot to cover. One cool topic from this week was solving systems algebraically. Let me explain. I really liked this part of the unit because you are letting… Continue Reading Week 12 – Pre-Calc 11
on This unit we’ve been tackling inequalities. Here is a little explanation on how to graph them and how to communicate all the essential information through a graph. First off, the dotted or solid line. No matter the shape, having a dotted or solid line is very important. It is paramount to remember that a dotted… Continue Reading Week 11 – Pre-Calc 11
on I don’t have a lesson in particular to quote today but instead a fantastic study habit I’ve picked up and want to try out post-mid-term. Basically, it’s a snowball effect of flashcards. As one lesson is completed, I make a cue-card or two and repeat until we have a unit test. Using this strategy, I’ll… Continue Reading Week 10 – Pre-Calc 11
on This week in pre-calculus I finally figured out how to solve quadratic problems with two variables! Let’s say we have two number with a difference of 18 and the sum of their squares is a minimum. How do we find the numbers? First off, we know We can also say And knowing that the sum… Continue Reading Week 9 – Pre-Calc11
