MC II B: I am not sure how to start questions 4.25, 4.26, and 4.30...
Could you possibly provide some minor hints to start the problems? Thank you.
Unfortunately, I am still stuck and may require additional hints.
Can you tell us what have you tried so far?
Yes. I'm stuck at the trigonometric identities because I can't seem to find any that satisfy and I have tried to add the two arcsines of the sines provided but it is not seeming to work out cleanly. Finally, I'm not sure how the third hint applies to the problem.
