OA is ‘n minuutwyser wat vanaf punt A
tot by punt B beweeg. Die hoek θ is
die hoek tussen die wyser se
oorspronklike posisie en sy latere
posisie:
3.1 Bepaal die koördinate van die
wyserpunt A in poolvorm.
3.2 Bepaal die koördinate van die
wyserpunt B in poolvorm.
3.3. Hoeveel sekondes neem die wyser om
van A na B te beweeg?

OA is a minute hand which moves from
point A to point B. The angle θ is the
angle between the original posision of
the hand and its later position:
Determine the co-ordinates of the tip of
the hand A in polar vorm.
Determine the co-ordinates of the tip of
the hand B in polar vorm.
How many seconds does the hand take
to move from A to B?
3.4 Bepaal die grootte van θ in grade. Determine the magnitude of θ in

degrees.
Convert θ to radians; round it to five
decimal places, since you need to use
it below in other calculations.
