Well boys, I did. I passed my pre calc final w 86%. Near the top of my class. I went from barely graduating highschool, ( all D’s, and I was in like freshman grade math at senior ) To complete turnaround in the last few years. I’m now working on a chemistry major, and couldn’t be happier. Men like this ( organic Chem tutor ) make it possible for me to follow my dreams. Giving me the help I desperately need. So, here I am thanking you OCT. you’re the man, and without your help I wouldn’t be where I’m at now! I’ll see you in a few weeks for trigonometry videos 😅
@@creativename4276 nice job buddy. You’ll do awesome. My tips for precalc are: make sure your factoring is up to date. Sum of cubes, difference of cubes, perfect square, all of it. etc etc. and just watch these types of videos if you get stuck. Some new ideas are introduced in precalc, transformations, zero theorem, series, graphing asymptotes. Etc. So just don’t sit at one problem for hours if you can’t figure it out. Search it up, or ask someone, and move on. But the factoring thing is huge, for you do it almost every single problem in almost the whole class. If you don’t know long and synthetic division, maybe brush up on that. Although they go over it as well. Overall, it’s an easy class. Just a lot of info. You got this buddy!!
I took precalc my junior year in high school. So dang man, nice. As for tips for precalc, don't overthink it. I'm assuming you're in advanced math, and already took something like algebra/trigonometry. Precalc is practically the same as that, but in a little more depth. Just use your time to understand all of the concepts as well as possible, as you'll rely on them in both calc 1 and calc 3. Calc 2 is it's own beast lol. Final tip, if possible, memorizing the unit circle is very helpful, but not necessary.@@creativename4276
Gen chem 1 and precalc right now, I cannot stress how much you’ve helped me this semester. And this video just now getting posted? Came in clutch I hope COVID has helped you and you have been able to help everyone else in online school during COVID.
@@castaben Damn how a year flies bro, ended up with a B+. Could’ve done better, but it is what it is. Least I passed. I assume you’re watching this video cause you got a Pre-Calc exam coming up. If so, good luck.
07:02 This video is a review for PreCalculus final exam questions. 14:04 Understanding properties of logarithms, including negative exponents and change of base formula. 21:06 Converting logarithmic equations to exponential and using exponential growth formula for investment problems. 28:08 Illustrates power of compounding for long term savings 35:10 Negative numbers inside a square root give imaginary numbers. 42:12 Factoring out the greatest common factor for a rational function and writing the domain in interval notation. 49:14 Explaining how to evaluate logarithmic equations and composite functions. 56:11 Graph absolute value and exponential functions using transformations and domain and range.
Thanks I am going to pre calc next year as I'm in 8th grade rn. This looks pretty simple! Thanks for helping other people including me. I may have to watch ur videos next couple years in highschool
I'm a college student. I've been focusing so much on chemistry that I was behind in precalculus and finals week is here. I've been stressing so much about it, but I found this video. Thanks for making it!
This stuff really works. I struggled with calc all my life and finally got it through this video and the videos on Patreon, definitely worth it! Thank you again!
I actually have tears in my eyes you just made me learn everything about log in less than an hour yet my class last year left me confused and behind in log alone.
Just got an A for my overall grade in my college precalc class, thanks! I had a hard time in 10th and 11th grade math but this video was great for filling in the gaps. I was scared I would fail the final exam so I’m very surprised but y’all this did actually help a lot. I for some reason struggled with log and natural log equations bc I never grasped it in the last few years
Used one of your other UA-cam videos, Pre-Algebra Final, to help my son get into Honors Algebra as a 6th grader. Great problem selection and explanation. Looking forward to use this one to work with my oldest son.
Watching this depressed me a tiny bit given that… I just took my final today. If I had just watched even this small portion of your exam review! I probably wouldn’t have made the mistakes I know i did. Almost all of your questions lined up exactly with what was on this final.. wild 🙃
For question 8 use Vieta's formulas which relate the coefficients of a polynomial to the sums and products of its zeros. For a cubic polynomial f(x) = ax^3 + bx^2 + cx + d, the sum of its zeros is given by -b/a. In this case, a = 1, and b = -3, so the sum of the zeros of the polynomial is -(-3) / 1 = 3
Been watching these videos for a while and it really helps since i cant focus in class when I'm easily distracted. I'll give an update on how it was my finals in 5 days
a quick way to solve the sum of the roots of the cubic polynomial on 21:59 would be -b/a where b is the coefficient of the x² term and a is the coefficient of the x³ term. additional info: the product of the roots would be -d/a where d is the constant.
Thank you! I am taking University entrance exam tomorrow .they said I need to have a high school level knowledge of math and they give guidelines: logic, matrix, function, logarithms, trigonometry and graphing. I think this is enough to review before my test. P.s I am away from my studies like 3 years and now trying to get into university. I believe it will help
All stakes are high in my precalc class, im so close to passing but just one percentage off, im going to no life it tomorrow and the next day, Thursday's my final exam, wish me luck.

I think you should mention in 47:39 that the reflection go first then 3 units up, because it was a bit confusing when you reflected the graph not by Ox, thank you
ya, graphing order of operations is always left/right, then anything immediately associated with “x” (reflections, absolute values within a function), then stretches and compressions, then at the end up/down
Looking at these while in IM3, nothing really seems hard here, I just don't know the rules and vocab yet. Guess calculus will start to be hard, this won't :D
Since 80% of our pre-calculus exams rely on tools like Python or GeoGebra, the recent change in exam format-removing 50% of the first half and incorporating it into the much larger second half-means that many of the topics covered in this video are irrelevant for me and others in the same situation. We're allowed to use any 'non-communication' tools available, including certain websites, but this makes the content less useful. I would appreciate it if you could provide videos focusing on topics related to digital tools like GeoGebra, integration, and vectors, especially addressing more complex problems that cannot be solved without these digital resources.
cross multiplying is basically multiplying the denominator by its reciprocal on both sides. Ex: 1/4 = x ---cross mulyiply 4x=1 or mulyiply both sides by 4 to get rid of the fraction. This only works if there is a fraction in the equation.

very helpful, i cant imagine what would my grade look like if I didn't see this video
For problem #3 you could use a log with a base 3. Then you don't need a calculator.

how did it go?

for question #7, why do we not convert 40 years to months, or 12 months to one year? Does a problem not require the time units to be the same?
The ratio is per year, so 12 times per year is every month. 0.09%, 12 times per year for 40 years essentially

Can you make one for Chemistry 1 and calculus 1?

My final is Thursdays praying I remember 😁
not me just starting to study 2 minutes before my exam
Thank you so much
At 3:21 does anybody understand why he cross multiplied and what the rules are for cross multiplication?
cross multiplying is basically multiplying the denominator by its reciprocal on both sides. Ex: 1/4 = x ---cross mulyiply 4x=1 or mulyiply both sides by 4 to get rid of the fraction. This only works if there is a fraction in the equation.
3:40 why do we switch the x and why?
To solve for the inverse, and finding the inverse is simply swapping the x and y coordinates.
You want to solve for y in terms of x
