@@H1289-h8o yea sort of the only thing we have not covered is proof by induction but, for us that wont come in our exams. I will assume you also do normal a-levels if so volume of revolution is should be easy(well I found it easy).
It won't come up, its not something that is in the specification. A lot of the formula book info is from old specifications. One question where you would use that formula is something like write down the matrix representing the transformation in the line y=(3)^1/2 x
Thank you these videos are very helpful as I am revising for my Y12 exams right now.
Have u finished whole of Core pure year 1? We have got V. Of revolutions and vectors left

You're so goated
I’ve just realised they give the formula for a transformation to do with tanx, however in the textbook there are no questions on it, can it come up?

Yeah I've never seen it so I assume no
For question 2 what if i have a multiple of the answer?
Hi for question 6a, is it possible to do it by solving simultaneous equations
13:25 how do you know that plane z = 0 must be 0x + 0y + z? why is there 1z?
z=0 can be written as 1z=0. 1z=0 can be written as 0x+0y+1z=0
@@rtwodrew2 for Q6 is it a given fact that the z axis is pointing down? How do we gather that?
