Suppose that A is a second quadrant angle with sin A = 1/4. Determine the exact value of sin (A/4).
I'm clueless. May someone help please!

Do you understand why that answer is correct? If you don't, ask!
People here are desperate to talk to anyone who isn't claiming relativity is wrong and Einstein was a nut case.

This is about as close to a clue as it gets without punching the numbers for you.
Do you have a sin-1 key on your calculator. Try keying in 0.25 and hitting it, then divide this number by 4 and hitting the sin key. hey presto you have done some basic, very basic maths.

Carry on, Flummoxed. I think I need to go for a drink.
That's always a good option. Do you have a bar onboard your ship, within easy walking distance. I am guessing there might be a some waves of a sinusoidal nature, If you are in an ocean with just a breeze. Equator or Polar

Not a drop allowed aboard ship. We are presently in port though.

So far I'm still waiting to talk to someone who can support Einstein and refute his theory wasn't fraud. I don't go so far as to say the experimental results supporting the facts of relativity were also fudged as some here people do.
