This channel will contain video math lessons for some of the courses that I teach. Currently there are all the Trigonometry videos posted. I am currently beginning to work on AP Calculus AB videos. And, hopefully coming soon will be the videos for my College Algebra course.
On occasion, you may also find videos pertaining to my cross country and track teams as well.

This problem shows how to solve a 3x3 linear system of equations. It already has a 2x2 system in it, so we will begin by solving that system and then substituting the solutions into the remaining equation to find all three variables. #maths #mathinstruction #algebra #systemofequations

Couldn't you distribute the 4 making 4x+12=36 and then solve for x. The answer is still 6
X = 6 or x = -12
Thank you 👍 sirji god bless you
Thank you
Which profession is this necessary in and how? Honest question.
Matrices are very common in programming
Why does it go left 1?
❤
Wait, shouldn’t it be -228? 3:14 mark Ah, just saw the correction Love these videos btw, I’m no good at math but these videos really help me review a lot
I love this
Why do you times it by 3 at the end of the equation? Are you supposed to always times them but didnt because the others were 1? Please explain
Yes, I times by 3 because the numerator of that fraction was 3. You can think of times by 1 on the other fractions as their numerators were 1, but I didn't explicitly state that.
Thank you for these videos im learning more in weeks from you then i did years in high school.
if you need this for your job you should be getting a special class for it, instead of having it shoved into everyone's business making them more stressed.
Wrong, negative signs 😮😮😮
You'll have to explain... the solution as presented is correct.
I still dont get it
Yes
Thank you for this, it helps me a lot to understand clearly the process. Big 👍
Why aren't your video views increasing? And not reaching people? The reason is: 1. Your video is not being SEO properly 2. Your video is not reaching the right people 3. Not using video hash tags properly 4. Not sharing the video on social media There are a few more reasons. That's why your videos are limited to your channel. Can't get out In a word, your video is awesome. Such videos are in great demand. If you do these things correctly. Hopefully, you will get a lot of visitors. Feel free to ask me any questions.
Very helpful you deserve 100m subscribers😢
while doing fractions, why did you use the ''denominator'' 20 and not another number?
thank you good sir
omg you saved me thank you so much jim i love you
Can anyone expalin how he got negative 7x on the 3rd step of the 2nd equation?
Can we represent diameter as DAF
You're a a real one dude. Thank you.
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
thx i really appreciate it
I'm so weird... that pen fidgeting at the beginning makes my skin crawl. 😅
*Promo SM* 😔

Good point. This is a Speed solution. I went through all 60 x 1mn this morning. It was so fun.
Maybe a better way to teach this would be to graph this with an XY grid. Show, (2,1) then explain it's the midpoint of a line. Show point C and infer the other half of line. These are wonderful videos
If I’m “teaching” it, yes I’d agree. If I’m doing the problem for speed (which I am on a timed test) this is my approach.
Excellent videos. You never circle D in this one, but you do say it. My lord, I wish I had you as a teacher prior to taking the SAT
Sorry to ask which topic is this?
i think its complex numbers
Who does matrices in a calculator??
Americans apparently. Pretty sure we weren't even allowed calculators for the linear algebra exam
I effortlessly use the APA format but have no idea what this high school test is asking. What's a "matrices"? 🤣
Lots of people including me for A level Math. it’s saves lots of time. suppose you’re given A & B all 3x3 to show that (AB)^-1 = A^-1B^-1. I’m not gonna try to act genius 😂 at the end of the day all we need is to pass just show the process and punch those numbers in😂 no messing around.
@@wakeful3282 oh yeah I forgot ap math was the beginner level. Since we don't use terms like that here it all gets a bit confusing. Here linear algebra is a course all engineers, physisists and mathematicians have to take. It would be after you finish your first course in mathematics on a university level (Mathematical analysis of one variable) and calculators were not allowed during those exams. Calculators are usually only allowed when the important part of the exam isn't being able to do math, it's being able to understand the equations and which situation they might be used in. Like thermal-fluid sciences.
@@Lt_Lobster you a Mechanical Engineer? 🤣🤣 me too
as someone not from the U.S.... are you telling me your math tests are multiple choice? tf?
Not all tests are, but the ACT is.
IT IS CHRISTMAS BREAK. I DO NOT WANT TO LEARN ABOUT MATH DURING CHRISTMAS BREAK. I HOPE YOU HAD A GOOD CHRISTMAS.
Wrong
3/4 = .75 < 5/6 = .83
It’s -5/6, not 5/6… negative sign is small and hard to see but it’s there.
541
this is like 4th grade math though. Isn't it?
Calculator? For zeroes? Lame
I came to say the same thing lol. If you're already writing the problem out (which i recommend anyways) you're going to spend more time typing in the math on a calculator than if you just worked it out in your head.
This is the easiest question ever dfuk ☠️
Wait... is this current day math? I solved it forwards and backwards and got 90...
That’s z-score
❤❤❤
Oh my God, it's Albert Einstein
first but where is everybody?
Looking for who asked
Bruh go to sleep
You know math is boring when you spin your pen ahah
