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

Answer:
29.3
Step-by-step explanation:
4x+12+5x+3x-4=360
Add the X's up & move the numbers w/out factors (X's) to the 360 side. This will look like 12x=352
Then, you divide each by 12, leaving you with x=29.3
Might be wrong, let me know and I will rework it.
Answer:
If a scatter plot has no association then it's ordered pairs have no predictable pattern.
Step-by-step explanation:
Karen sells 7 hot dogs per hour while Henry sells 14 hot dogs .
