Sharp Estimation Type Inequalities for Lipschitzian Mappings in Euclidean Sense on a Disk

Some sharp trapezoid and midpoint type inequalities for Lipschitzian bifunctions defined on a closed disk in Euclidean sense are obtained by the use of polar coordinates. Also, whose partial derivative is considered. A new presentation Hermite-Hadamard inequality convex function its reverse given. Furthermore, two mappings H t id="M2"> h considered to give some generalized case that functions disk.
