How does trignometry work in circles?

Asked 242 views1 answers

I don't understand how they work in circles. Also How can i apply trignometry to scripting... Some stuff I don't understand with trigonometry ----

http://wiki.roblox.com/index.php?title=Terrain_Generation

I also have no idea how this works... May someone please explain how each line works. especially the math parts ...

for i = 1,40 do

y=100*math.sin(i)

p = Instance.new("Part") p.CFrame = CFrame.new(Vector3.new(100*i, y+100, 0)) p.Size = Vector3.new(8,8,8) p.Anchored = true p.BottomSurface = "Smooth" p.TopSurface = "Smooth" p.Parent = game.Workspace p.BrickColor = BrickColor.new(26)

end

This question already addresses basic trigonometry. You can find many more resources with Google (both on ScriptingHelpers and off).

If you plot y = sin(x) you get a shape called a sine wave.

It's smooth, and it's bumpy. This makes it very useful for making natural looking motion, such as swaying (taking math.sin(time)) or hills (taking math.sin(x) or math.sin(z)).

You can add more sine waves of different sizes / frequencies together to get more complicated but still smooth waves.
