A constrained extremisation Problem is expressed
as longsonge-multiplier problem with objective
functional.
I [X³ X] = √ [√x² ² + y² + 3 2 _k (t) (x²+ y² +3²_R²) ]dt
where x = dxc etc. and intereral has appropriate
fixed limitat
with fixed values of Xoy and
7 at the endpoints.
a). Explain what geometric problem is solved fiere and
Is there a local or global constraint.
