At 6:02 91/13=7 not 6
Also note that at 6:18 y=x/2-z/3+2 is a plane, not a line

Wish my high school classes were just in an isolated room watching these videos in peace and quiet, and then coming to the teacher for 5 m for remaining questions at the end of the day. I can do math like this but not when there are so many noises around. Thanks for these vids, this makes me rediscover math in a fun way.

|6-18+8+12| = 8 -> the answer for number 3 is 8/7

[Cristiano_an]

thanks bro you helped me alot i can't express my feeling.

[Jepleg]

10:04 shouldnt it be 6-10+12? cuz idk how -18+8 is +10 it should be -10?

[ameenah]

10:01 There was a mistake. Negative 18 plus 8 gives Negative 10 (-18 + 8 = - 10). So the final answer is supposed to be 2.

P.S: I love your teaching.

This video is the first time I've seen TOCT use a pink colour in, must be a special one.

MR. Organic Chemistry Tutor, thank you for the examples that shows How to Find the Distance Between a Point and a Line in 2D and 3D Geometry. The last two examples contain math errors that was corrected in the comment section.

[mariatheresagadia]

6:02 hmm.. I think you were mistaken?😁 It must be 7, right? Anyway, the video is great. Thanks.

[Benedict_Miriti]

Point of correction The Organic Chemistry tutor while solving the second example of this video, 91/13=7 units not 6 units.Otherwise i enjoyed the video.Thank you.

[ninadshetty]

people who have doubts can never miss this channel, they will somehow get to know

[cvvyjel]

I will just say... I can't thank you enough.

[battleaxesam]

I was just planning on asking whether you had coordinate geometry and mathematical induction..Thanks.

#2 d=7
#3 D=8/7
Although i think #3 is wrong and the formula to get the distance for that number is different, since its a plane.

[kiks]

I have a question: In exercises in which the distance is given when graphing the line I'm having trouble figuring out the relative position of that line when I only have it's general equation.

Since I don't know where exactly the line should be I don't know which one of the two values is the right one.

[eloygy]

Should I rationalize the root if the radical is irrational (because on the examples, the roots are equal to whole number, while mine are decimals)

[fredericrust]

thank you chem man you saved me for 1 calc bc problem that i had no idea how to do and idk why i need to know this equation for it but thanks <3

[johnjoseph]

I like your videos_ they are awesome but in this video there is a mistake or error : 6 -18+8+12 = 6+8+12-18 = 26 - 18 = 8

[ameliabuns]

I wish you explained how we got to this formula!

[youssefhelwa]

Hey, quick correction -18+8= -10 not +10 so the final answer changes. Otherwise, great explanation!
