Harder Vector Questions 2

[@Sebastian98234]

Essentially: Find two different STRAIGHT lines that hit the point "X." They should both have the same scale factor, usually given as the variable, 'k.' TIP: (Make sure to apply the same rules when determining a straight line, e.g given a line 'ABC,' find the line segment AB, then AC.) find the equivalent vector equations of the two straight lines, where using another variable may be needed --- this sets up a simultaneous equation TIP: (Generally, you'll have to find a portion of one straight line, line segment AB for example in the first tip. You'll then to find another vector equation equivalent to line segment AB. Try and see if you can form one by going on a different line [look at a point, which is a midpoint to line CD or a point that has a ratio {e.g point F located 2:3 on line CD} that somehow attaches itself to point 'X.'] TIP: (think about the two lines as two linear graphs hitting the point 'X,' easier to understand when applying the skills for simultaneous equations) Match common factors in directions (put the direction 'a' as an equation, same for direction 'b') e.g 4a - 6ak + 2bk = -4bx - ax turns to: a /// 4 - 6k = -x b /// 2k = -4x Solve for k. Finally, read the question: is it asking for: A ratio of portion (of the line) : full (line)? (e.g line ABC where AB = kAC) k can be a whole number or a fraction, depending on the ratio. [portion:full] or [full:portion] OR A ratio of [bigger/smaller] partial (of the line) : [bigger/smaller] partial (of the line)? (e.g line ABC where AB = kBC) k can be a whole number or a fraction, depending on the ratio. [big:small] or [small:big] Hope this helped clear things a bit, if you're struggling. Goodluck for the paper 2 on Monday (if your doing last min revision like me lmao)

thanks for making this! there aren't too many examples of this type of vector question available anywhere else except past papers, so it was very helpful, very much appreciated :)

goat is single handedly saving my gcse maths rn

[@justaracoonchillinginatoilet69]

pfp source? and lol same but doing a levels and wanna make sure i remmeber how to do vectors

[@Zxrlorn]

Thanks, I understand practically everything now and I'm feeling ready for the exam tomorrow.

[@Kababsauce]

Same bro I mean this topics the only one I don’t know

[@ricardo-c4l7l]

Thank you. Very clear explanation of how to set up simultaneous equations and equating coefficients to solve for 'k'. I was stuck on how to set this up before viewing your harder vector videos!

[@paulinewanguiobaga]

thank you so much I have been stressing about vectors very badly! this was so much helpful.

[@emerging1374]

Same, good luck with tomorrow

[@michaelswahla4927]

basically all you do is find 2 alternative path ways on straight lines to the vector compare coefficients find the values of both coefficients boom

[@ramoplayzreal]

21:06 I find it far more simple to make both of the equations equal a value of x, like 36/15(x)=4k & 36/15(x)=6. so that is 4k=6, k=3/2.

[@markbaird8356]

You have a great way of explaining things. I wish you did some higher level stuff to cover uni level. Was looking for equation of a plane at the moment but missing being able to use you videos when I moved to uni level engineering maths.

[@primsiren1360]

im so confused as to how you know which vectors to make equal each other. In the parallelogram question you do AX = AX but why cant you do AX = AM like you do on some other questions like the one after?

[@mohammedreiyan7075]

Ur situation is similar to mine

[@pryfy7746]

Primsiren that's because point X has to be on both line PD and AM and because the lines only meet at one point that is point X has to be. (Hope this helps)

[@primsiren1360]

@@pryfy7746 i get all of them apart from the last. he literally uses random vectors that don't even have anything to do with AX and XM apart from being on the same line and somehow knows how to get the answer

@@primsiren1360 A bit late but this video explains the concept very well kzbin.info/www/bejne/jIHdm3qljZ2XoJY&ab_channel=RDrew

[@costrix5697]

@@primsiren1360 It's because in the parallelogram question, PX=kPD (PX is smaller and PD is bigger) which means that k had to be a fraction. This is why chose the smaller line (AX) to be equal to itself. In the next question OD=kOB (OB is smaller and OD is bigger) which means that k is an actual whole number and not a fraction, which is why he used the bigger line to be equal to itself

brother what is this questions

[@coolguy3943]

These are some mad questions... pretty sure you don’t even get taught this stuff in class

We sure don't.

we get taught this stuff in a level maths not gcse wtff
