Is it a compounded interest or is it a monthly or yearly compounded interest?
The correct option is the first one. Independent events are exactly what you're asking for: the information you have on one event doesn't affect in any way the probability of the other.
A classic example is the roll of two dice: assume that you roll the first one and get a 4. Does this imply anything on the outcome of the second die? No, all events 1,2,3,4,5,6 are still equally distributed, no matter the result of the first die.
cos (arctan (1))=
arctan (1) = 45 take it to the third quadrant = add 180 = 225
cos (225) = -1 / sqrt(2)
never leave a sqrt in the denominator
= -1 /sqrt(2) * sqrt(2)/sqrt(2)
= -sqrt(2)/2
sin (arccos (1/2)
arccos (1/2) = 60 take it to the 4th quadrant -60 degrees
sin (-60)
- sin 60
- sqrt(3)/2
