A man walks along a straight path at a speed of 4 feet per second. A searchlight is located on the ground 20 feet from the path and is kept focused on the man. At what rate is the searchlight rotating when the man is 15 feet from the point on the path closest to the searchlight?

Find the derivative:

y = arccsc (x/2)

I know how to find the derivative of the inverse of sin, tan, and sec, but I do not understand how to do the inverse of csc.

I hope this makes sense?

A ladder 10 feet long rests against a vertical wall. Let A be the angle between the top of the ladder and the wall and let x be the distance from the bottom of the ladder to the wall. If the bottom of the ladder slides away from the wall, how fast does x changce with respect to A when A=pi/3?

For what values of 'a' and 'b' is the line 2x+y=b tangent to the parabola y=ax^2 when x=2?

I need to find the coefficient of friction for a lab I did last week. We used carts with plastic, cork, and felt bottoms on an inclined plane. We put various amounts of weight in the carts. We then elevated the inclined plane to the point where the cart began to slide and then used a protracter to measure the angle of the inclined plane. I have the normal force and the angle. How can I find the coefficient of friction? (I understand that the (coefficient of friction) = (force of friction) / (normal force)

solve for x:

ln(ln(x))=1

I will be getting out of high school soon and I have the most amazing boyfriend in the world! We're so in love. I know that many people on here say this and sound immature, but he is everything to me. He is the love of my life, my best friend, a shoulder to cry on and a someone who can always cheer me up. We both believe that it is important to wait till you're married to have sex, so we aren't physically attached, its deeper than that.

The problem is, I am almost positive that I have the opportunity to attend the United States Naval Academy, which only a tenth of applicants are accepted.

I know that I can't completely base my decision on my boyfriend, but I can't not take it into account. I would love to hear from couples that are in the military or have been. Thanks for your help
