So I basically do not understand why the grades changes. ( English isn’t my first language sorry btw). For example :

(-I)^5: 1^5(cos(-450)+isin(-450)
Stays like that and the grade doesn’t change

But here

32( cos 1020 + isin1020)
32(cos -60 + isin (-60) )
32 ( cos 60-isin (60))

The grade (1020) does change

So basically I don’t get when I have to change it or not

it doesn't matter

#

it's whatever you understand

#

I would change -450 though
