This man needs an award... well done, thorough explanation that didn't want to make me fall asleep. This will really help me on my math tests/exams. Many thanks!
OMG, THANK YOU!!! I knew nothing of logs and you simplified so well. Our regular classes turned into online classes because of the virus and I was almost in tears. The videos we had to watch did not explain it this way. It just said memorize.Thank you!
why in the world you weren't my teacher at school.....i love this guy could he be the best math teacher in the world....im in 2018 and this guy from 2014 helping me more than anything....thank you so much..............
A good way to check complicated logs (like x = 199/95) is to calculate the left side of the equation and then divide by the right side of the equation. If they are equal (as they should be) , then the answer will be 1. Be careful, you might have to use many parenthesis while plugging in the equation.
Thank you, I need algebra or any math to be worked out step by step and explained why everything was done... this is helping my wrap my head around logarithms.. all the symbols and powers make my brain panic before I can even solve it.
He's making me pay attention at least. His face feels like home. I love him. My passion came fast but it is founded in puns and his understanding of logarithmic equations.
Studying for finals right now and I knew everything but this and solving exponential equations because I forgot them this was so useful I'm answering practice questions right before my final next class
4:45 If when you add logs you multiply the subject, shouldn't that equation work? Multiplying -1 and -4 should give you a positive 4. This leaves you with log base 2 of 4 which, as established, equals 2 thus allowing X to be both 4 and -1.
If you are unfamiliar with the quadratic formula, then you can use completing the square, factor method, and square root method to solve. In all honesty if you know those 3 you should know the quad by heart.
I love your math vids. I am an old timer catching myself up on math. I would like to see you work vsome practical appllication problems in engineering, chemistry, physics...biology. Both regular and natural logs. Please consider it. Thank you.
Just play some techno or retro background music and this video feels like the a tutorial from the 80s-90s~ Thanks man this was definitely helpful. If I were to tell you something, it would be that a *log is an exponent*!
