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 :)

• Maths - Typo? -

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

• Maths -

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
