Hardest Topic - New syllabus (1 Viewer)

[pine-apple01320]

Which topic do you think is the hardest in the new syllabus for 4u maths?

 

[jarodphillips_]

some of the proof questions are crazy

 

[ewjfiwhelowaeoplg]

Vectors <= Mechanics < Integration < Complex Numbers <<<<<<< Proof

(Both the topics themselves and typical exam questions)

Wouldnt be so sure vectors will be easy. Alot of material in textbooks is, but the actual stuff they put up is nothing like whats in the textbooks.

 

[po45gp]sedorgmjkpoerdjgf]

I'm only about a third done with course but I'd say probably integration<(Mechanics+complex numbers)<vectors<proofs

 

[HeroWise]

Someoen put insanely difficult proof question uwu

 

[ewjfiwhelowaeoplg]

Yeah I think you are right.

Almost all hard vector questions will probably derive from this dot point:

• prove geometric results in the plane and construct proofs in three dimensions

 

[CM_Tutor]

You can be given vectors questions in projectiles that make things challenging

Literally just substitue the line equation and solve for lambda in |v - c| = r for i, then for ii make a sphere of radius r and centre a, b, c, then use vector rules to find expressions for other points in the question, sub into the formula and prove that it equals 0.

Just tests the theory, not the application

can you show this in extended working please?

 

[hschelper01]

I'd say - from what I've seen - the proof questions look like they are very challenging

 

[5uMath]

can you show this in extended working please?

Hope this helps. Correct me if im wrong (see attachment), I dont know if there are solutions to the paper

thanks so much!

can someone show the working for part 3 of this question please? been stuck for a looooonnnnggg times lol

sorry i meant part 3 of this question

also 5u, in this solution of yours you mentioned use part (i), what is part (i)?

 

[mathsbrain]

can anyone help?

 

[5uMath]

can anyone help?

This was from the sample from nesa. Part i asked prove that a *(b+c)=a*b+a*c (dot product)

 

[mathsbrain]

Hmm I fail to see how this hint helps with part (ii), are we talking about the same Sphere question that's on this page? Do you happen to have the link for the nesa sample link?
