Give an expression
The minute hand on a clock is 8 cm long and the hour hand is 5 cm long. Give an expression for d, the distance between the tips of the hands, in terms of a, the angle between the hands.
I've been trying to figure this out for the past hour... needless to say, I just have problems with these questions.
It would seem that this is a classic application of the law of cosines.

Can you simplify?
