Can you do an example with the Vector product?
Makes soo much sense now. Thank you 👏💯
😱👍🏿thank you tb
you are my savior🎉❤
Will you cover scalar product form (r.n=k), distances from the origin (the formula given in Edexcel), and converting planes to cartesian from scalar product?
(These are all core pure for edexcel)
Scalar Product form r.n=k is equivalent to n_1x + n_2y + n_3z + d = 0 form: ruclips.net/video/iTySP1g1ECk/видео.html
Distance from a point to a plane, using the formula: ruclips.net/video/pDF18aX3Tp8/видео.html
Planes are already in cartesian form if given in scalar product form r.n=k
What two non parallel lines are contained in the plane?
I know that n_ would be the cross product of their direction vectors but what about the position vector? Can I use a point from either line or does it have to be the point of intersection?
thank you
For Edexcel, the vector product isn't part of core pure but the spec does say
"Understand and use the vector and Cartesian forms of the equation of a plane"
So do we have to use this method? Or what are they expecting us to know? Thank you so much for your videos
It is perfectly acceptable to learn and use the vector product even though it is beyond the specification - you won't lose marks for using more advanced methods.
"Understand and use the vector and Cartesian forms of the equation of a plane" does not refer to the vector product and you do not need to learn it, but it can be very useful.
@@TLMaths thank you
why cant you use bc vector, it shws that in the book snd its annoying me
you can use the BC vector. so as long as you use 2 vectors that are on the plane you're good
