Answer:
Start at the origin and plot the points.
Step-by-step explanation:
For A, start at the origin and then go 4 units to the left.
For B, start at the origin and then go 4 units up.
For D, start at the origin and then go 4 units to the right.
For C, start at the origin and then go 4 units down.
Answer:
G=23/16
Step-by-step explanation:
Replace x with π/2 - x to get the equivalent integral

but the integrand is even, so this is really just

Substitute x = 1/2 arccot(u/2), which transforms the integral to

There are lots of ways to compute this. What I did was to consider the complex contour integral

where γ is a semicircle in the complex plane with its diameter joining (-R, 0) and (R, 0) on the real axis. A bound for the integral over the arc of the circle is estimated to be

which vanishes as R goes to ∞. Then by the residue theorem, we have in the limit

and it follows that

the first answer choice, associative property of addition
