polygon?

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.

[@justadude721]

He offers more than just chemistry perhaps his other videos may still benefit you

Parallel vectors → Parallel angles(opposite angles equal to each other) → (solved: two sides and one angle known) → Law of cosine → Done

[@justadude721]

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]

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

[@justadude721]

@@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]

@@justadude721 tbh with you, the mathematical method guarantees higher accuracy than graphical.

[@justadude721]

@@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

[@Adfelix23]

The scale method is only suitable for two perpendicular vectors

how do you know which method you have to use and when? The parallelogram method or the triangle method

[@favourebubechi6659]

Thank you bro. This was really helpful

Nice thanks sir I’m always satisfied

sir what about polygon method?

[@maheletmahelet795]

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

[@primekidus9419]

But how do we find the direction suing the parallelogram method? Please respond fast, my test is on monday

is the angle correct?

[@m4srx]

You can use the given angle and use the formula c2=a2+b2+abCosc

[@totoval4362]

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?😅😅

[@EdilawitWondimagegn-nk4zs]

A square plus b square plus 2abcos teta i gueass this is the right formula u add - before 2ab

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?

[@mangomanlassi7779]

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

guys this is wrong he should use A^2 + B^2 + 2ABCOStheta not -2ABCOStheta

[@user-hr8kf8ss5h]

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.

how he get the 120° #respect

[@justadude721]

Corresponding angles He shifted the left side of the parallelogram to the right as F1 and F2 shouldn't be pointing towards each other

[@thesciencehubskb]

Interior angles add up to 180 degs 60 degs + x = 180 degs x = 180 degs - 60 degs x = 120 degs

[@amogus436]

​@@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

[@zunayedsafi5396]

Wrong formula

It's right
