Answer:
The integral is 0.
Step-by-step explanation:
A parameterization of curve C can be:
X (t) = cost 0 <= t <= pi
Y (t) = sint 0 <= t <= pi
r (t) = costi + sintj
r '(t) = -sinti + costj
The integral is given by:
Consider two integers . We say that
is a multiple of
if
is evenly divisible by
:
Alternatively, we can say that is a multiple of
if there exists an integer
such that
So:
- 4 is not a multiple of 4, because 4/8 is not an integer.
- 8 is a multiple of 8, because 8/8=1
- 20 is not a multple of 8, because 20/8 is not an integer
- 40 is a multiple of 8, because 40/8=5
