Standard Equation for trig function: y = A cos (B (x - H))+ K
*Here, we are just dealing with A (amplitude) and B (period)
Period = 2π/ b

8 = 2π/ b
Solve for b: 2π/8 or π/4

Equation: y = 2 cos (π/4 (x))

All proportions have this form:

$\sf{\dfrac{a}{b}=\dfrac{c}{d}}$ , Where $\sf{\dfrac{a}{b}}$ is equal to $\sf{\dfrac{c}{d}}$ .

If $\sf{\dfrac{a}{b}\neq\dfrac{c}{d}}$ , it's not a proportion.

_________________________

Here we have two pairs of numbers:

40,10 and 32,8.

Written As a proportion, they look like :

$\sf{\dfrac{40}{10}=\dfrac{32}{8}}$

Hope this made sense to you :)
