how to write sine wave algorithm code

[ilyas besli]

I have a problem.
My course homework is about draw sine wave
and I must do this in java.
How do I do this.

for any help, Thanks...

Well, do you know how to write a program that draws a line, circle, or other picture?

[ilyas besli]

yes, I know draw line, oval, rectangle etc.
But I could not understand how to draw sine wave.

Something like this?

for x = 0 to picture width
   compute y with your sin algorithm
   draw a dot at x,y
next

I'm sure you'll have to multiply x & y by some scale to make it fit the screen. Give it a try and show us what you make. Then we'll know exactly where you're stuck. Or not!
