Your friends have opened an ocean fishing operation that requires their fishing vessel to cross a channel, where the depth of the water (in metres) varies with time, and is represented by the following...

I really need a lot of help in math, it's my worst subject. My best is English, but that's not important.

Find the tension in each cable necessary to keep the block from moving (either sideways or downward)

A 900-lb block is being suspended and held stationary by two steel cables as shown. The first cable (to the left of the block) makes a 70 degree angle with the horizontal, while the second cable...

Evaluate In degrees: 1. Sin^-1 (-2pi) 2. arctan (- square root 3/3) 3. sin (cos^-1(- square root 3/2) Evaluate in...

I have a few more questions about stuff like this, but all my questions are going on here separately. I think I'm STARTING to understand this stuff a little better. I just can't figure out how to...

I really need to get corrections done as quickly as possible. I need help. :(

Please help! I am really stuck on this one....

My professor said for this problem to use inverse trig functions, half angle, and double angle identities. Evaluate: tan(2sin-1(4/5)) Please list the answer...

Using the pythagorean identity, find the value of sin⊗ and tan⊗ if cos⊗= -1/2

Explain why sin⊗2 + cos⊗2=1

Solve for ALL values of x in the real number system. If an EXACT solution does not exist, round your answers to the nearest hundredth. sin2x = sinx

Solve for x in the interval... 0<x<2π: 3sin2(2x+1)+2sin(2x+1)-1=0 My teacher says there should be 6 answers. I have a TI-84 calculator, so maybe...

One end of a 9.3 foot pole is 13.6 feet from an observer's eyes, and the other end is 17.4 feet from the observer's eyes. Through what angle does the observer see the pole?
