in the 7th question i waiting for him to realize what he did lmao .

2023-10-17 16:04:06 +0000 UTCI'm not sure if there is a quicker way but if you plug in the t values back into that cos(PAB) equation, you'll get 41 degrees for the -2/3 solution which is the acute angle. You'll get 120 degrees for when t=-2 which is what we need. Hope this helped.

2023-10-06 07:58:14 +0000 UTCIn question 9ii) of the worksheet, why do we reject the -2/3 solution? How can I confirm that it gives the solution for an acute angle?

2023-06-18 13:13:23 +0000 UTCwhy in questions 2, we proved in part 1 there is no intersection, but part 2 we found the angle between the 2 lines ? how is this possible ? if there is no intersection how is an angle formed ?

2023-04-17 02:50:11 +0000 UTCsir, can you make on plane questions also for vector, the questions which involve plane are very tricky to understand

2023-04-14 18:31:45 +0000 UTCfor the third question. isnt directional vector of PA and l also perpendicular? why do we use the vector equation of PA?

2023-03-30 13:35:32 +0000 UTCWhy would it matter? If the question specifies radians use radians, if degrees use degrees. Both units are describing the same thing.
Intuitive
2023-03-03 10:03:29 +0000 UTChi, do we use radians when dealing with angles in this chapter or degrees?

2023-03-03 06:47:43 +0000 UTCSir I tried taking the OB point vector and the results are not the same for me, I redid it with the video and ended up with a 7 as my m value My constant values were also different. Could you please solve this query of mine

2023-01-04 13:23:27 +0000 UTCFor Question 17, it said AB=2CD, i tried equating the vectors themselves but it didn't work and then i saw that you've worked it using their magnitude. So how do i know when i should vector or magnitude and why didn't equating the vectors themselves work, like what is the reasoning?

2022-06-24 05:46:18 +0000 UTCJust any point on the line is fine you will get the same result :)
Intuitive
2022-05-14 06:30:39 +0000 UTCin question 1, when we take a point to create an equation for line(m). you took (1,-2,2). I thought we were supposed to take the starting point to create an equation or is it that we can use any of the two points?

2022-01-16 20:20:44 +0000 UTChii in the worksheet question 15, can you explain why does OC= OD+AB??? i cant imagine itt
good boy
2021-10-30 15:56:42 +0000 UTChello, can you also do mechanics solving papers videos? thank you

2021-10-13 10:17:05 +0000 UTCMay i know when you will upload that video

2021-08-26 10:53:16 +0000 UTCI'll start looking at that exam after P3 along with Mechanics. I hope the P3 exam hack series is helpful a lot of work went into it.

2021-08-11 13:24:34 +0000 UTCHey! since your stats1 was a absolute life saver could you please do stats3 as well
Roooooha
2021-08-11 12:33:24 +0000 UTCYep I'll be doing that question last. I need to do Numerical Solution and then I'll do that video.
Intuitive
2021-08-10 19:53:08 +0000 UTChey ! just wondering if you did a worksheet for polynomials and reminder therom
