If an angle is uncertain, then the sine or cosine of that angle will be uncertain too. Just calculate
the function (sine, cosine, etc.) for the largest and smallest angles allowed by the angle
uncertainty limit and note the resulting range of results: This is just the “brute-force” method, but
it works fine.

We are here to "Help" you clear your concepts but it seems that you think we are here to "Do your homework".
I'm sorry that way you won't be learning anything and it sort of kills the idea of "Assistance" ... right?
