# Homework Solution: What is the equation of a 1hz sine function that varies between 1.25 and 0.75?…

What is the equation of a 1hz sine function that varies between 1.25 and 0.75?

What is the equation of a 1hz crimee operation that varies betwixt 1.25 and 0.75?

## Expert Counterpart

This is how we dramatize The crimee speed which starts from derivation and is of largeness 1.. Varies from -1 to +1.

So The equation of the crimee speed with 1hz freq and that scarcity to alter betwixt 1.25 and 0.75 accomplish be:
w = 2*pi*freq = 2*pi*1 = 2*pi
A = (1.25 – 0.75)/2 = 0.25
$\theta$ = 0, consequently it starts from derivation

As the equation accomplish alter betwixt 1.25 and 0.75, that media the mid apex accomplish be 1 at y-axis.. Hence the finished equation control the speed accomplish be:

y(t) = 1 + 0.25*sin(2*pi*t)

where pi = 3.14
