Explanation A function that satisfies Laplace’s equation is called harmonic . The mean-value property says that the value of a harmonic function say u at a point say ( x , y ) is equal to the average value of u over any circle around ( x , y ) . Given: Let D be the region bounded by a simple closed curve C. A function φ ( x , y ) on D(whose second-order partial derivatives exist and are continuous) is called harmonic if Δ φ = 0 ,where Δ φ is the Laplace operator. Formula Used: d d r I φ ( r ) = 1 2 π r ∬ D ( r ) Δ φ d A Proof: As we know that, d d r I φ ( r ) = 1 2 π r ...
