Pierwszy punkt

Δl₁  =  10m

$$\varphi_{1} = \frac{\Delta l_{1}*\rho}{2R} = \frac{10*60}{2000} = {0,3}^{g}$$

c₁ = 2Rsinφ₁ = 2000 * sin(0,3) = 9, 42

x₁ = c₁cosφ₁ = 9, 42 * cos(0,3) = 9, 42

y₁ = c₁sinφ₁ = 9, 42 * sin(0,3) = 0, 04

Δl₂  =  50m

$$\varphi_{2} = 0,5*\varphi_{1} + 0,5*\left( \frac{\Delta l_{2}*\rho}{2R} \right) = 0,5*0,3 + 0,5*\left( \frac{50*60}{2000} \right) = {0,9}^{g}$$

c₂ = 2Rsinφ₂ = 2000 * sin(0,9) = 28, 27

x₂ = c₂cosφ₂ = 28, 27 * cos(0,9) = 28, 27

y₂ = c₂sinφ₂ = 28, 27 * sin(0,9) = 0, 40
