please help and show work! i really do not understand any of these problems! you don't need to answer all of these problems, hopefully at least one :3

sin²(3x)-sin²(x)=0

cos(x/2)-sinx=0

cos2x/sin3x-sinx (minus) 1 = 0

Question

please help and show work! i really do not understand any of these problems! you don't need to answer all of these problems, hopefully at least one :3

sin²(3x)-sin²(x)=0

cos(x/2)-sinx=0

cos2x/sin3x-sinx (minus) 1 = 0 <- the minus one is not part of the fraction!

thanks! you have no idea how much you have helped me!

whats the question exactly?

anonymous · Answer

the questions are listed up there.

they are:

sin²(3x)-sin²(x)=0

cos(x/2)-sinx=0

you do not have to do both, whatever you are able to understand because i don't :/
