Consider the following scenario:
We have a number of sequential building blocks (e.g. 12 building blocks , ordered from 1 to 12), distributed randomly (but not necessarily equally) on a number of builders (e.g. 3 builders ). The builders are required ...

TRIGO SOLVING HELP!!? Hi, I think I know how to attempt this question, but I realized that I was unable to factorize! Please help, would appreciate it so much!
Use factor theorem to factorise 6c^3-19c^2+c+6=0
therefore solve 6cos^3x-19cos^2x+cosx+6=0 ...

Thus....
Thus is not a factor.
To factor the given polynomial:
I would use the rational roots theorem, which states that if has rational roots, it will come from the list:
I like integers, so beginning with the positives, let's check:

I am stuck on this one.
csc^2 = 2cot + 4
I did the pythagorean identity and my equation becomes
1 + cot^2 = 2cot + 4 and ended up at
(cot - 3) (cot +1)=0
I think part of my answer is 2pik + 3pi/4, or is it pi k + 3pi/4? and 5pi/4? But what about cot=3...

Greetings,
I'm trying to teach myself contour integration/complex analysis and
finding it a little more challenging than I expected. To make a long
story short, it's not obvious...

Thus, the
integral from t=w to t = pi-w has magnitude <= R*exp(-rRc)/R * (pi-2w)
= (pi-2w)*exp(-rRc), so goes to t=w is <= R*w/R = w; and similarly....
So for any small w <= t <= pi-w, so |integrand} <= exp(-rcR)/R for such w.

I am trying to find the value of t, when phi = 60? or pi/3 radians.

x = 8 + 2 * cos(pi*t);
alpha = atan(8/x);
beta = acos(sqrt(x^2 + 64) / 40)...

In mathematical, not programatical ....
Typed exactly

phi =
pi - atan(8/(2*cos(pi*t) + 8)) - acos(1/20*(1/4*(2*cos(pi*t) + 8)^2 +
