A) f (x) = 
- 3
Step-by-step explanation:
A clock is a circle which is 360 degrees.
There are 12 hours -----> 360/12 = 30 degrees.
Going clockwise, add 30 degrees for every hour the hour hand is at.
There are 60 minutes -----> 360/60 = 6 degrees.
Add 6 degrees for every minute the minute hand is at.
Find position of both hour hand and minute hand, then take the difference.
Time is 5:15.
Hour hand is at 5 plus 15/60 or 5.25.
Multiply by 30. 30*5.25 = 157.5
Minute hand is at 15.
Multiply by 6. 15*6 = 90
157.5 - 90 = 67.5 degrees.
Answer:
well at 0 degrees on the unit circle the point is (1, 0)
Let 
. Then
and substituting these into the ODE gives
Let 
, so that 
. Then the ODE is linear in 
, with
Multiply both sides by 
, so that the left side can be condensed as the derivative of a product:
Integrating both sides and solving for 
gives
Integrate again to solve for 
:
and finally, solve for 
by multiplying both sides by 
:
already accounts for the term in this solution, so the other independent solution is 
.
