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
First term (a) = -15
common difference(d)= -9-(-15)
= -9+15=6
So,
12th term(a12)= a +(n-1)d
= -15+(12-1)×6
= -15 + 11×6
= -15+66
= 51
Answer:
1 ) y = 2x - 1
slope = 2
y intercept is (0,-1)
2) y = -1/2x + 5
slope = -0.5
y intercept = (0,5)

<h2><u><em>
x = -2.27272727273</em></u></h2><h2><u><em>
in fraction</em></u></h2><h2><u><em>
x = -25/11</em></u></h2>
<u><em></em></u>
Step-by-step explanation:
Solve for X
6x+60x+150=0
66x = -150
x = -150 : 66
<u><em>x = -2.27272727273</em></u>
<u><em>in fraction</em></u>
<u><em>x = -25/11</em></u>
