(1 k) <--- this was the matrix form in the shear, right?
(0 1)

yes u are right

(1 0 is what i got :/
k 1)

wrong

The 2nd question in the exam,
the lines of symmetry question was: I and O
and the order of symmetry was I, O and N.. PLEASE SAY RIGHT!! :'(

Yeah I feel unsure about that bit too
but umm I didnt write O in that cuz O has more than 2 lines of symmetryh. circle right? so i assume it has many

[Cregg Davids]

what u guys get for the gradient?

 

[Cregg Davids]

what you guys get for the graduent?

Hey! how can you find 2 x 2 matrics of the transformation of ( reflection, rotation, enlargement, shear and stretch) ?

 

[bluefa1con]

what u guys get for the gradient?

i got -1.67
but if u differentiated the equation the most accurate answer is -1.5
but -1.6--1.7 should be in given range
