Math help please
I want to go to sleep but right as I'm about to my friend messages me on Skype asking for homework help since he just started school today and I don't want to go to sleep feeling bad for him, I'm not great at math myself.
What's sin(2x)=1 all the solutions? Thanks.
Nvm I'm going to bed.

goodnight love
Good niight !
sin(2x)=1
2x=pi/2, 5pi/2, 9pi/2, 13pi/2
x=pi/4, 5pi/4, 9pi/4, 13pi/4
4 solutions because you need to do 2 revolutions for 2x (3 for 3x and so on).
ok sleep tight! !
