oh i think i see it,
so since v and g are constants you don't differentiate them
therefore,
dR/dx = (v^2/g)(2cos2x)
and then
0 = v^2/g(2cos2x)
so in order to make the equation equal 0 the angle has to be 30 degrees is that correct ?
would this be the right answer?
the derivative of sin2x is cos2x(2) = 2cos2x
but we were informed that log differentiation ln was to be used ?
But I'm still stuck. Could you help me further

Hey guys, this is my first post and of course first question to ask of calculus
Alright well I had this test and we had this very difficult question that I could not solve, it was in the hardest section.
