How would you graph sin 4x = 1 ?

a) How do you find amplitude?

b) How do you find Period?

I'm kind of confused about the "=1" part.

Thanks :)

I am also confused. That is not the equation of a wave.

Could it be

L = sin 4 x ?

in that case the amplitude is 1

and the period is when 4 x = 2 pi

or x = pi/2

so period is pi/2

and this can be written

L = 1 sin 2 pi x/.5 pi
