hey guys im trying to make sum y=sin, cos and tan x graphs but i dont no how. im trying a method where i use for statements to draw graphs but im getting sum wild results. heres my code

Private Sub cmdSin_Click()
For z = -360 To 360 Step 0.1
x = z
y = 1000 * Sin(x * 1000)
picGraph.Circle (xOrigin + x, yOrigin + y), 1
Next z
End Sub

my teacher insists that he says the graph. but i dont c nething.

thanks for the help
