Here's a little "analogue clock" example I threw together...

SuperStrict

' analogue clock example by BaH, showing use of Cos and Sin

Graphics 200, 200, 0

Local radius:Int = 98

' set the origin to the clock center
SetOrigin 100, 100

While Not KeyDown(KEY_ESCAPE)

	SetColor 255, 255, 255
	
	Local time:String = CurrentTime()
	Local hours:Int = time[..2].toInt()
	Local minutes:Int = time[3..5].toInt()
	Local seconds:Int = time[6..].toInt()

	Cls
	
	' draw face
	For Local deg:Int = 0 Until 359
		Plot Sin(deg) * radius, -Cos(deg) * radius
	Next
	
	' draw hour segments
	For Local deg:Int = 0 Until 359 Step 30
		DrawLine Sin(deg) * radius, -Cos(deg) * radius, Sin(deg) * (radius - 10), -Cos(deg) * (radius - 10)
	Next
	
	' draw hour hand - 30 degrees per tick
	Local deg:Int = (hours Mod 12) * 30
	DrawLine 0, 0, Sin(deg) * (radius/2), -Cos(deg) * (radius/2)

	' draw minute hand - 6 degrees per tick
	deg = (minutes Mod 60) * 6
	DrawLine 0, 0, Sin(deg) * (radius * 0.8), -Cos(deg) * (radius * 0.8)

	' draw second hand - 6 degrees per tick
	deg = (seconds Mod 60) * 6
	SetColor 255, 0, 0
	DrawLine 0, 0, Sin(deg) * (radius*0.75), -Cos(deg) * (radius*0.75)

	Flip

Hope it helps.
