  • Increasing Coordination

    • Increasing coordination helps organizations to maintain efficient operations through communication and control.
    • Coordination is the act of organizing and enabling different people to work together to achieve an organization's goals.
    • Coordination is simply the managerial ability to maintain operations and ensure they are properly integrated with one another; therefore, increasing coordination is closely related to improving managerial skills.
    • The management team must pay special attention to issues related to coordination and governance and be able to improve upon coordination through effective management.
    • In practice, coordination involves a delicate balance between centralization and decentralization.

  • Introduction to the Polar Coordinate System

    • The polar coordinate system is an alternate coordinate system where the two variables are $r$ and $\theta$, instead of $x$ and $y$.
    • When we think about plotting points in the plane, we usually think of rectangular coordinates $(x,y)$ in the Cartesian coordinate plane.
    • The distance from the pole is called the radial coordinate or radius, and the angle is called the angular coordinate, polar angle, or azimuth.
    • The radial coordinate is often denoted by $r$ or $ρ$ , and the angular coordinate by $ϕ$, $θ$, or $t$.

    • As applied to coordination chemistry, this meaning has evolved.

  • Double Integrals in Polar Coordinates

    • In $R^2$, if the domain has a cylindrical symmetry and the function has several particular characteristics, you can apply the transformation to polar coordinates, which means that the generic points $P(x, y)$ in Cartesian coordinates switch to their respective points in polar coordinates.
    • The polar coordinates $r$ and $\varphi$ can be converted to the Cartesian coordinates $x$ and $y$ by using the trigonometric functions sine and cosine:
