How can you reduce this cotangent cubed x into sin and cosines?

Would it be:
Cosine divided by sin cubed where only the sin is cubed or do both the top and the bottom of the fraction get cubed.
In essence, how do you reduce it?
Thanks for answering!

How is nuclear radiation different in an X-Ray Machine than a Nuclear Bomb?

I heard that X-Ray devices use nuclear radiation and I also read that nuclear bombs also use nuclear radiation.
So, what is the difference between the nuclear radiation in the two devices?
there are a couple types of ionizing radiation, that is radiation that can ionize molecules in your body by kicking electrons off them. When this [...]

How do I find the slope and x and y intercepts of a given line?

I’m doing algebra homework and I’m stuck on a series of questions that use the directions mentioned in the title of this post.
I have to find the slope and x, y interceprs of the following:
y=3/5x-9
Can anyone help?
to find x-intercept, plug 0 for y
to find y-intercept, plug 0 for x
y = mx + b
m = slope
b= [...]

What is the probability that the team will win by more than X points?

Say a team has a probability W of winning a game. Also the probability of a team winning by X or more points is P+ and the probability of winning by exactly by X points is P.
As practical example say a team with a winning probability of 58%, and the probability of winning by X [...]
