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
