We obtain the formulas for analytical integration of dominant function components derivatives with respect to the arbitrary straight-line segment and arbitrary segment of circle. These formulas allow high-precision calculating of the stresses inside the deformable area. The effectiveness of using the formulas is shown on the example of solving the homogeneous tension problem for plate with circular hole.
