What effects does multiplication,division (etc...) have on math.sin,math.cos and math.tan?

What effects does multiplication,division (etc...) have on math.sin,math.cos and math.tan? May you please give me a list of effects on how these operators work on these trig functions.

**For example: **

print("Tehgeek's weird sinewave loaded...")
n = 0
spd = workspace.SpeedSine
tab = {}
position = workspace.SineStart.Position
xx = position.x
yy = position.y+10
zz = position.z

for i = 1, 20 do
p = Instance.new("Part")
p.Name = "BRICKSINE"
p.Size = Vector3.new(1,1,1)
p.Anchored = true
p.Parent = workspace
table.insert(tab,p)
end

while wait(0.1) do
if spd.Value ~= 0 then
n = n+1
div = n/spd.Value
for i = 1, 20 do
v = Vector3.new(xx,math.sin((i/2))*5+div+yy,i*2+zz)
tab[i].CFrame = CFrame.new(v)*CFrame.Angles(math.sin(i), 0, 0)
end
end
end

The last sections with the variable v confused me with the y slot where it has ... math.sin((i/2))*5+div

This part confuses me with the math? May someone give a thorough explanation. Also- Funyun - your explanations confuse me alot. Last thing can someone explain the div variable and how speed even works out with this variable - > div = n/spd.Value

Your question is more of a pre-calculus question. You can take a look at links to find out what certain things are, such as amplitude and a vertical shift.

Perhaps it's even a better idea to understand what tan, cos, and sin are. They are highly important functions that basically set the base for all trigonometry. They coordinate with how angles of triangles function with most of time, circles.

1. Pull out a graphing calculator. Make sure it's on radian mode.

2. Graph y = x. It's a diagonal line going up.

3. Graph y = sin(x). It's a wave.

4. Graph y = sin(x) + x. It's a diagonal wave going up.

Get it?
