trig

[grand wolf]

bro its just a bit of pythagoras

then sohcahtoa

[fringe cypress]

not even

theta = 45deg because its half of a square

because the two sides are equal

so sin45 which is (sqrt2)/2

[grand wolf]

ye that works as well

[ornate quarry]

I was questioning why I got 1/root2 for a sec 🤦‍♂️

[lime fjord]

that’s clever

i didn’t think of it like that

[fringe cypress]

that isnt wrong, its just not the proper form. you need to multiply top and bottom by sqrt2 so you get sqrt2/2

[hollow lance]

Tbh, I prefer non rationalised form I use it much m

ore

[jolly terrace]

tan45 😔

[fringe cypress]

thats fair but

in the question

it will always give you in rationalised form

[lime fjord]

why’s ur year role still year 11

[fringe cypress]

like this was multiple choice and it wasnt there

[lime fjord]

i’ma change mine tmr to year 11

[jolly terrace]

No clue

[hollow lance]

Yeah tho i just mean it doesn’t really exist in “peoper” form the more maths you do

[fringe cypress]

i meant proper for that question

[hollow lance]

and u should be able to convert or just know

[ornate quarry]

Oh that makes sense

[fringe cypress]

yeah but this person didnt realise that they were actually right

just not in the correct form for this question

[hollow lance]

ya I do agree w u

I was just thinking that at gcse it was always drilled into us that we should use rationalised form

But like the more maths I do
