Monitoring is the regular observation and recording of activities taking place in a project or programme. It is a process of routinely gathering information on all aspects of the project. To monitor is to check on how project activities are progressing. It is observation; â systematic and purposeful observation. Monitoring also involves giving feedback about the progress of the project to the donors, implementors and beneficiaries of the project.
The arctangent of x is defined as the inverse tangent function of x when x is real (x ââ). When the tangent of y is equal to x: tan y = x. Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: arctan x= tan-1 x = y. Example. arctan 1 = tan-1 1 = Ï/4 rad = 45Â° Graph of arctan. Arctan rules
The Lindhard function of free electron gas is so elementary that its closed form can be obtained in clarity. Despite its simplicity, some nontrivial physics manifest. In 1D, the divergence of static response function ($\omega=0$) indicates the well known Peierls instability and the system tends to break its translational symmetry.
