Hey guys

I was wondering if the "Rotation of a point about the origin" (Circular Functions) is in the 3&4 course and whether or not it's examinable?
The one with the transformation formula :


I can't find it in the Study Design but we did this in 1&2

[pi]

Nope, not on the course

[monkeywantsabanana]

Thank you!

VCAA need to clean things up a bit.
I cant understand why transformation matrices are even in the 1&2 syllabus.
I did this stuff in UMEP maths last year and it is clearly undegraduate level Linear Algebra

Well there is some relation to linear algebra. But really if you know how to multiply complex numbers, or at the very least know how to expand then this matrix form is just really the same thing just in a different notation. Morale: in VCE there are easier ways of handling rotations etc. so I can't see this by itself being useful.

What is the one way you can write on your calculator? something to do with ?

[abd123]

Write

[monkeywantsabanana]

Oh yea, I forgot about that but I've seen it somewhere... there's another way writing it with e, pi and i

Is there? I wouldn't know were the bit of would got to in a , so where would the multiplied factor exist in the eulers form of any sort complex number given?.

Wouldn't the multiplied factor be in front of the eulers number, I'm taking a stab in the dark.

EDIT: I found out that  equals to so its possible for an multiplied factor to take place.

Ah... It seems like not sure where the goes...

[monkeywantsabanana]

Where is this even useful?

EDIT: I do actually mean

I assume you already have your CAS calculator in Polar form. Take this is an example


Hoped I Helped

EDIT: should used codefigs to make less mistakes in latex.

Ahh yes, thanks very much for that

No.



It is called the 'exponential form' and it is not part of spesh 3/4

[monkeywantsabanana]

Though, it may be useful if typing into the calculator 'cus there's no
