Thank you! This helped a lot :)
wow! thank you sir, I finally understand this now
But you only forgot about q = -D/4a where D = b²-4ac
Hi I was in matric 2017 and I was supplemented I then wrote it 2018 and still failed I then wrote in 2020 and still failed the two subjects I wrote were maths literacy and life sciences I wanted to know do I qualify to combine those failed results cause I read that if you have more than 20% on those failed subjects ,and you pass 5 other subjects you qualify to combine your results I saw this on Skills Academy is that true ?
Thank you for detailed explanation, It helped me with formula understanding :)
when he was about to 10%, me: 👁👄👁
living in turkey bought a new car for 40.000 liras sold used for 300k
Thanks for the video! If anyone in the comment section from AUS was wondering, he uses arc Tan instead of inverse Tan but its basically the same thing.
whT ? I DOMT SEE ANY INTEGRATIONNN
Thanks Sir. It helps a lot!!
best of the best
How can compounded interest be lower than simple interest?
10 years onwards, still very helpful. Thank you so much.
Its interesting this equation rearanged is also conservation of energy.
❤❤
Hey thanks alot for this video but I tried to answer manually even without knowing yet the formula. On the first sample problem I got the answer correct, but on letter b. I tried again manually computing based on how I analyzed the question and I arrived at the value 138067.1924 I tried checking where I possible made a mistake but when I tried solving using the formula turns out the answer is same with mine. Sorry to correct you sir perhaps you mis typed on your calculator hehe the correct answer is not 130,000+ but 138067.1924
Thanks sir
Question: what happens if the interest rate is 0 %? The FV should be n*a? What trick do you apply to the formula?
x+x(1+0)+x(1+0)^2+x(1+0)^3+...+x(1+0)^(n-2)+x(1+0)^(n-1) = x+x+x+x+...+x+x =nx So if you have a 0 interest rate and you make n payments of x then you have nx saved.
Extremely helpful! love that you show the calculator part! I was struggling with that in class.
thank you so much
Pleasure!
Thanks
Where can I find past papers for Sacai?
Now Bread is R18 ,R19 almost R20 after 10 years. 😃
It would be more beneficial if you would have explained along with help of excel
cheers
Hi Today I went to the western cape department of education in cape town I told them that I want to combine they gave me a form then I payed they only wanted my copy of ID and not both statements and they didn't ask me what subject I want to combine they just said I will be get a message in like 4 to 6 weeks to collect my certificate. I wrote my matric in 2021&2022 . Are they going to choose for me what subjects should I combine or they will just put the new percentage and not included the old percentage
Memorizing the names of the polyatomic ions is a way better idea because some tests will not have the periodic table
So, I’m just here looking for the next video in the series. I see it was nine years ago and I am just getting to a now. I guess I’m a little behind as usual. Oh well maybe someday it will show up or I will find it :-)
Explain the effects of task on sinking fund
Where does the future value formula come from?
Let me know the name of the method? It's looks so easy ^o^

At 5:06 mark , you wrote $130,067.19 which is incorrect. Always double check your work in math problems. Simple but costly mistake.
Hi... i have a ask, I did my matric in 2015 and i decided to upgrade mathematics and Life science of which i passed them well, i went to department of education to combine and now i have a new certificate.My question is will they allow me to combine my results again if i decide to upgrade another subject now?Thanks in advance
Yes, you will be allowed to.
When they reprinted ur certificate was it a ASC or NSC? And did u upgrade in June?
You just saved my life. Thank you for this video
Thank you so much! This equation just jumped out of the textbook with no context and it was wracking my brain trying to make it make intuitive sense. This video perfectly and succinctly explained the derivation and now I'm not confused anymore. Thanks!
Very helpful ❤❤❤❤❤❤❤❤❤❤may jesus Christ protect you and bless you
Thanks for sharing! I posted a video on completing the square using remainder theorem. Hope to get your feedback.
Can two lower grade pass be combined for a better mark?
Hi Ezra. I don't think so - if I understand what you mean. Which subject did you pass on Lower grade that you want to combine?
I did matric in 2006 and passed only five and failed one,so in 2022 I upgraded my matric with two subjects maths lit and geography and I passed them so how can I combine then since I was told I'm not qualified to combine them,is the Amy options because I don't want to carry two certificates.please advice🙏🙏🙏
Well you should be able to get an endorsement or exemption certificate from the Matriculation Board. mb.usaf.ac.za/ Go to their website and try that.
U have a REALLY good voice. Really cleared things up for me! thanks.
Great Video!
