Top 5 Things I learned in Math 10

Here are the ‘Top 5 Things I learned in Math 10’

1.Trigonometry

When we first started this unit I had no idea what to expect because quite honestly I never really heard or did anything about trig. The word is kind of big and made me think that it would be super hard but in reality it wasn’t at all. Using the new buttons on my calculator was a big change for me since I had no clue what sin, cos, or tan was before this unit. SOH CAH TOA was definitely one of the most helpful acronyms I’ve learned in school and I will forever keep that in my mind. I felt this unit was so important to me because I felt a sense of satisfaction after completing the questions because of all the work that went into it and finishing with the correct answer, along with learning something completely new and actually understanding it was a good feeling.

2. Substitution and Elimination

With this unit I personally thought it was going to be hard and difficult to understand at first, but as we went along in class I came to the realization that it wasn’t bad at all and it was very doable it was just kind of time consuming. One very good thing about this unit though is that you are allowed to check if your answer is correct or not by inputting your results into the original equation to check how you did. I was also glad that I got to learn something new that I couldn’t do before but now I have not such a huge problem with.

3. Functions

When we first started learning about functions I wasn’t paying as much attention as I should have but still took all the notes. As we gradually went along it started to make more and more sense to point where I was comfortable with doing the questions. This unit gave me a good understanding of input (x) and output (y) and how to solve lots of functions.

4. Slope, x/y intercepts, and different forms

In grade 9 I got introduced to slopes and how to graph lines based on them but I did not understand it at all. When we started learning slopes and intercepts in this class I finally began to comprehend it more and do really well on the questions. I eventually became very comfortable with doing slope related questions and converting them into different forms like point slope form, general, and slope y intercept form. It was then easy for me to graph lines and do linear equations.

5. Arithmetic Sequences

This unit was definitely one I understand the most and I quite enjoyed it. I learned how to find the common difference what arithmetic means, how to find which term a number is, and whether or not a number is part of that particular sequence. I do wish we had a unit test though because I felt that our grades and especially me personally could’ve risen up quite a bit. I think that this unit was unfortunate that it had to happen so late and in a very time lacking period since we had finals coming up but I still managed to learn a lot and comprehend all the information.

Math 10- Week 17

This week I learned about arithmetic sequences, more specifically what terms are and how they are related to the numbers in sequences. First off arithmetic sequence means that the pattern of numbers all go up by the same amount each time. The first number of a arithmetic sequence is called term 1, the second number is term 2, and so on… You can be able to find the pattern or common difference of the sequence with the multiple terms listed. Once the common difference is found then you multiple that by each term to find out how much you need to add or subtract to get the final equation.

Math 10- Week 15

This week I learned what elimination was in the sense of applying it to systems of equations. For elimination to work you would need to 2 equations on top of one another as if it looks like you’re going to add them (you are). First you would need a zero pair which means both equations have to have either the x or y value be opposite from each other like -5 and 5. Once you have a zero pair, cross it out add all the other numbers. If there isn’t already a zero pair, you would need to make one by multiplying one of the equations to equal a zero pair to the other.

Math 10- Week 14

This week in math I learned what substitution for linear equations were. Substitution as you may already know is when you take something out and replace it with something else. In math we did that with equations. First we start off with 2 equations and choose which one to rearrange so either x or y equals to something. Then input the rearranged equation into one of the other equations’ variables in brackets then solve. Once you’ve found the answer, input that into the rearranged equation and you should get the other variable’s answer. Once completed verify the solution.

Math 10- Week 13

This week I learned about different forms of writing slope and y-intercept equations and being able to graph them. One specific one I’m going to talk about this week is point-slope form. Point-slope form is what I would consider and many others to be the most useful form because you’ll be able to branch off of that one to get to the other forms (general and slope y-intercept). Point slope form requires knowing the slope and a pair of coordinates/ordered pairs, from there you would subtract the y value from y and insert an equal sign and on the other side put the slope and in brackets to indicate multiplication, insert the x value subtracted from x.

Math 10- Week 12

This week I learned how to calculate distance and slopes for a line on a graph. To calculate the slope of a line you would need to take the y values from each point and subtract them from each other, then do the same for the x values. Then you put the difference over the sum and that should give you the slope. To determine whether the slope is positive or negative is noticing which way the line goes, reading the graph from left to right. If the line starts higher going down it’s negative, but if the line starts lower going up, it’s positive.
