## Homework Statement

A particle is projected with an initial speed u from a point at a height h from the horizontal plane. Find the equation for maximum range of the particle.

## Homework Equations

R=u^2sin2θ/g

H=(usinθ)^2/2g

## The Attempt at a Solution

Let me assume the angle of projection to be θ. Then the total range of the particle can be given as:

Rt=u^2sin2θ/g + √(2h/g)*(ucosθ)

For finding the condition for maximum range I will have to differentiate this expression. But, I'm not able to convert this expression in the form of just one variable.Please help.
