Thread: Calculus Differentation using Trig

A projectile thrown is thrown over level ground. at an angle x to the ground has a range R given by R = (v^2/g)sin2x where v is the initial speed in m/s and g = 9.8m/s^2. Determine the angle of projection x for which the range is maximum.

the max value for will occur when

how could you tell without calculus...or if you had to use it?

if , then what is the largest possible value for ?

that actually makes sense, thanks for the clarification

this question is out of 6 marks, there has to be some sort of work i would have to show to get my answer...

You've been shown how to do it. It's expected that you can fill in the details.
