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
In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just 'cot'. Of the six possible trigonometric functions, cotangent, secant, and cosecant, are rarely used. In fact, most calculators have no button for them, and software function libraries do not include them. They can be easily replaced with derivations of the more common three: sin, cos and tan. Cotangent can be derived in two ways: The inverse cotangent function - arccot. For every trigonometry function such as cot, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. So the inverse of cot is arccot etc. When we see arccot A, we interpret it as the angle whose cotangent is A.
