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 posterior cricoarytenoid muscles function to rotate the arytenoid cartilages laterally, thereby abducting the vocal cords. Their action opposes that of the lateral cricoarytenoid muscles. The lateral cricoarytenoid muscles function to rotate the arytenoid cartilages medially, thereby adducting the vocal cords. The main function of the transverse arytenoid muscle is adduction of the vocal cords.
