Thank you. Now, how would you calculate the natural log of 3 without a calculator? :)

I want to know how you would do log 5 without a calculator and without knowing the value of any other logarithms. No one ever explains this!!! I can't find it anywhere!!!

same. Even if I ask this to AI, AI just invents random stuff like "Use magic" or "Count your fingers".

Thank you ! you took a bug out of my mind since at school they explained logarithms but it wasn't clear where the calculation of the mantissa came from!! it seemed like a secret, you took the values ​​from the log tables and that was it!

Grazie ! mi avete tolto un tarlo dalla mente da quando a scuola spiegavano i logaritmi ma non si capiva dove veniva fuori il calcolo della mantissa !! sembrava un segreto , si prendevano i valori dalle tavole log e basta !

Thanks for such for such a clear explanation!

I hope this knowledge remains with me in the future.

i was hopping to come here and learn thing like log of 13.5 base 2 or sth less obvious lmaooo. isnt there a similar method to long division for square roots or ... to find the log of sth in base 2?

Curious why a comma is used instead of a decimal point? Seems like it might be confusing if you are writing a decimal number or separating a set of numbers with commas.

Commas are sometimes used like a decimal point in Europe

I need a teacher like him.

great channel. Thanks!

HI sir, thanks for discussing this conceptual part of the log function... I have a qn at 5:28 Can we also write loga(b) = log(b) / log(a) Instead of loga(b) = ln(b) / ln(a)? Yuvraj from India.

Fantastic video

Thank you

4:47 can i just write the exact value ln(8)/ln(3)?

You are doing a great job sir !!!

Hmm. Great teacher. But the big mystery question for me was how were the values in the log tables calculated in the first place? Or, alternatively, how does my calculator calculate them? You had me excited most of the way through the video, because I’ve been wondering this since high school (literally decades). It seemed like a dodge to me back then. “Boys and girls, the way you figure this logarithm stuff out is to actually not figure it out - you look up values in a table or press buttons on a calculator. That was the first time in my life a maths teacher left me hanging, intellectually. Anyway, although this video cleared up some algebraic techniques for me, ultimately the solution shown to figure out the value of a logarithm still ends up being, “look it up in a table, or press a button on a calculator.” Bummer.

I didn't watch the video. But from the comments, it seems the video doesn't tell how to calculate natural log without calculator. My guess is to use maclaurin expansion to calculate the log of the number's inverse and multiply by -1. For example, ln2 = -{ln(1/2)} = -ln{1-(1/2)}which can be expanded using maclaurin series.

But then, how the values of log tables were calculated in the first place?

please how do you calculate logs such that you can derive answers even non integer answer like log to base 10 of 7 ?

👍

Sorry teacher, without using calculator how does ln3= 1.09861?
