I always dreamt of the day where I could unsubscribe to your channel. I know that sounds weird, but chemistry was hell for me and I had to take it all the way to orgo 2. I graduated university last Wednesday. Just wanted to say thank you for all of the helpful videos, I wouldn't have graduated without the help. So happy to be done with this chapter in my life. For everyone in my past position, you can do it! Work hard and the success will follow you.
My teacher taught us to include a scale of maybe 1cm:10N and draw the vectors according to the magnitude and direction. After that he taught us to measure the resultant vector and use the scale to find the force.
@@mangomanlassi7779 my physics teacher used to teach math. He quit because he said the workload was too much and for some reason he rather not do stuff the math way.
@@mangomanlassi7779 true but sometimes in my exam papers they ask for an appropriate scale I also prefer the mathematical method as it's more accurate and less tedious but unfortunately I can't use it in some situations
thank u too much u are always helping me its best to get your tutor rather than to have teacher in home spending money for him, is better to spend titrabytes on your tutor. Im very glad of your tutor keep going
then split the vectors into x and y components, individually sum the x and y components, then take those x and y resultants and create a right angled triangle where you can use pythagoras theorem and inverse tan to get the full resultant vector
YOUVE ALWAYS HELPED ME WITH EXAMS AND I PASSED AND NOW I GOT A VACCATION AS A PRESENT BECAUSE YOUVE TAUGHT ME EVERYTHI G I NEED TO KNOW, SO I JUST WANTED TO SAY THANK YOU FROM THE BOTTOM OF MY HEART FOR HELPING ME FOR YEARS
Hey your understanding is too wrong, the formula used in the above tutorial is Law of cosines applied in for a triangle. While the equation according to you has theta equal to angle between two vectors with both tails of vector coinciding. Also the theta in law of cosines entitles for angle between the two vectors of head and tail coinciding consecutively.

He offers more than just chemistry perhaps his other videos may still benefit you
Congrats and good luck for your rest of journey
Thank you I will really make it as well in Jesus 🙏 name.
Congratulations @brookebain7250 thanks for the advice ☺️
Blud thinks hes the main character 😂😂😭😭💯💯💯🗣🗣

yeah same we learnt that too, i prefer the mathematical method though

@@justadude721 tbh with you, the mathematical method guarantees higher accuracy than graphical.
@@mangomanlassi7779 true but sometimes in my exam papers they ask for an appropriate scale I also prefer the mathematical method as it's more accurate and less tedious but unfortunately I can't use it in some situations
The scale method is only suitable for two perpendicular vectors
Parallel vectors → Parallel angles(opposite angles equal to each other) → (solved: two sides and one angle known) → Law of cosine → Done
Bro knows everything
😂😂😂
u posted just when i needed this :0 thank you so much!
If i pass physics class, its all thanks to this guy
I'm in the exact same boat. Best of luck to us.
I really needed this ! Thank you
Me too and thank to this guy, God bless youu❤
Please keep up with the good job. Excellent and entertaining.
I love your lessons you teach so well
Best math and physics and chemistry teacher
And biology too
thank u too much u are always helping me its best to get your tutor rather than to have teacher in home spending money for him, is better to spend titrabytes on your tutor. Im very glad of your tutor keep going
this man is my lord and saviour fr
Thank you bro. This was really helpful
Nice thanks sir I’m always satisfied
I didnt hear what you said at 1:17
But how do we find the direction suing the parallelogram method?
Please respond fast, my test is on monday
Physics master 🙏🙏🙏
🇪🇹?
@@primekidus9419አው and you ?
@@kangmoabel yes 😅
how long have You been watching the organic chemistry tutor ?
sir what about polygon method?
how do you know which method you have to use and when? The parallelogram method or the triangle method
Helpful, keep it up
You are the real mvp
Really helped. Thanks!
I do 1000 google searches and then finally come to here . This being the last search.
Thanks sir😊😊😊
A square plus b square plus 2abcos teta i gueass this is the right formula u add - before 2ab
Thank you so much for this video... I finding difficult with my textbook you made me understand everything
Very nice video
very usefulllllllllllllllllllllllllllllllllllllllll
Why are you breaking F2 and F1 into their respective Fx and Fy component before finding Fr?
Can someone plz help?
I really needed this! Thank you
I got R=140N, 30 degrees N.E..
I used a scale of 1N=.1cm to fit in a notebook😅😅. 7.3 difference. Very little difference right?😅😅
Thanks 😊
is the angle correct?
You can use the given angle and use the formula c2=a2+b2+abCosc
We meet again, old friend
Thanks sir!!!
Physics man🎉🎉😮
I've never learned 🤔this before
what if I use displacement instead of force
please tell me is this addition or subtraction?
If you are asked to find resultant then it means addition
What if you have 3 vectors? Does he have any videos on that?
then split the vectors into x and y components, individually sum the x and y components, then take those x and y resultants and create a right angled triangle where you can use pythagoras theorem and inverse tan to get the full resultant vector
@@mangomanlassi7779 bro you are a legend thanks!
@@mmbb7276 np haha, hope it made sense
then use POLYGON LAW
@@mangomanlassi7779 why not use POLYGON LAW
Where were you in my physics exam😭
You are so perfect
Isn't the formula is a²+b²+2abcostetha
Thx had problems with it
TYSM

I like it starboy
I love you.
Why it isn't "+2abcosC?"

Jan 1 🎉🎉 happy New Year bro 😂
Isn't the formula for R² is a²+b²+2ab cos theta
It's -2ab cos theta
why "-" in a²+b²+2abcos theta, isn't it ?
Exactly a²+b²+2abcos theta is right……
It's prob cuz cos⁰ was +, but if cos⁰ was ‐ then itll prob be +2....
Just sayin
I calculate I got -ve at -7200
Im learning it in my 5th and i wanna die
why you use cosine law? the question is use parallelogram not cosine law?
guys this is wrong he should use A^2 + B^2 + 2ABCOStheta not -2ABCOStheta
Hey your understanding is too wrong, the formula used in the above tutorial is Law of cosines applied in for a triangle.

repeat pls!@@user-hr8kf8ss5h
360degrees = 2pi
yay im fail yayyyy
But why negative guys
Who are you bro ?
cool person
Coolest person
batman
Bro show ur face plss
Ama fail
21700
how he get the 120°
#respect
Corresponding angles
He shifted the left side of the parallelogram to the right as F1 and F2 shouldn't be pointing towards each other
Interior angles add up to 180 degs
60 degs + x = 180 degs
x = 180 degs - 60 degs
x = 120 degs
@@thesciencehubskb but aren't triangle angle adds up to 180? so the angle that intersects F1 and Fr is 0? i don't understand the concept
:o
Wrong formula
It's right
