# Question: using lagrange multiplier theory show that the optimal angles are...

###### Question details

Using Lagrange multiplier theory, show that the optimal angles are given by,

n1=theta1+w(y2-y3)*(sec)^2*n1

n2=theta2+w(y3-y1)*(sec)^2*n2

n3=theta3+w(y1-y2)*(sec)^2*n3

where w is a constant that ensures the lines of sight define a single point of intersection.
