your existence means a lot to all those students who are struggling with mathematics, you're doing good job!

The only channel that make me watch a whole long vedio.. thanks as always !

[@klincollins1307]

God bless you for this video, you just save my life for my exam tomorrow. thanks

[@Leentt-y6f]

how tf he made the math look so easy?? fr I fall in love with him

[@SuhaanShah]

Thank you so much for this video! My honors algebra 2 teacher is absolutely horrible and can't teach if her life depends on it but you are really helping me out!!!

[@SrijanDevipur]

thankyou soo much i understood this in 28 mins while my prof took 3 hours and i still didnt understand

[@Aerosol4444]

Man the moment I see his video is the moment I start solving every question thrown to me.

Great video for students 👍

thank you so much!You are my saviour

thank you sir your video are so good , they clear doubts

[@tobifalodun7726]

Thanks for the log video

[@incog2678]

Thank you

[@mohammedms7623]

Your are so good

[@tobi2992]

11:38 why would I take the square root of both sides?
forget it. got it now. thanks for the video.

[@evernarten42]

lmao one day before the exam and i just understood logarithmic functions thysm

[@spillovereducationtutorial3228]

Explaining well.

[@kingmk3904]

this guy's face reveal is gonna be crazy

[@kazijawadahmed6488]

Thanks a lot man

[@preciousdesola-wm8bj]

Thank you so much

[@justadude721]

I love logarithm probably one of my favourite math topics

[@Jayb-ko1fk]

if this is your favorite then i’m sorry to say you’re insane

[@justadude721]

@@Jayb-ko1fk a lot of my classmates and other people I know love logarithm as well

[@DibyasaDas-k9f]

Are you crazy ?!

[@justadude721]

@@DibyasaDas-k9f nah. I mean it's better than trigo and geometry or stuff like that. I found it more manageable and so did most of my classmates. It might also be that my class was very strong in maths

[@DibyasaDas-k9f]

@@justadude721 Are you from India?

[@AnshulChauhan95]

Thank you!

[@snowvale8815]

Thank you! May I have aquestion why in the third example it goes from -infinity, when it should not be negative? Thank you

[@Mkdenn]

It would be because he divided a negative, which changed the sign from what wouldve been x > 6 to x < 6. Making the domain (-infinity, 6) instead of (6, infinity)

[@eytanhakim774]

good job

[@CyberGuard01]

Please can you upload a video for the range of logarithmic functions using the examples on this video..
Thank you in advance!

[@rukshanfdoable]

How to find the range of the function of the 1st question

[@baraa3368]

the range of a log function is always all values of R

[@imgayyyy2213]

​@@baraa3368 Yup

[@SannaBS]

nice videos

[@seumengkheang9350]

Do you teach IB maths AA as well?

[@rukshanfdoable]

Please tell me how to find the range of the function of the 1sr question

[@chonkeboi]

All real numbers I believe

[@Glancing_Dagger..]

equate it to y and solve

[@hiteshsharma3791]

use wavy curve method

[@grrlpaz2784]

11:36 why did you do the negative version?

[@Glancing_Dagger..]

if we do square root on both sides then we don't just get x-1 we actually get |x-1|

[@wolves-u7p]

thanks a lottttttttttttttttttttttttttttttttttttttttttttttttttttt

Let me show you guys one property of logarithms most teacher don't teach
Logb^a(c)=1/alogb(c)

[@yisahak]

Let me show you one property of logarithms most teacher don't teach

[@Glancing_Dagger..]

pls show the derivation

[@yisahak]

@@Glancing_Dagger.. logb^a(c) use this property logb(a)=logc(a)/logc(b). logb(c)/logb^a(b)=1/alogb(c)

I hate logs lol
