blah blah blah Can we please add National 5 (Nat5), Higher and Advanced Higher (AH) labels (i dont know what Higher counts as for the english level types)
so, when working out cosx + (√3)sinx as 2cos(x-60), it ends up being two different graphs, even though they are supposed to be same (i think?)
i don't know why this is because doing the working that i've been taught (since the method could potentially be wrong or i'm missing a step), it results in 2cos(x-60)

#

unless 2cos(x-60) is meant to be some sort of altered form of cosx + (√3)sinx, but i don't think that's what we were told

oh i think its cuz

#

desmos isnt in degrees

#

u can set it to that tho

#

try

#

2cos(x-pi/3)

#

it will be the same

#

or
2sin(x+pi/6)
