Role-Play Scenario Tips continued Scenario #3 â Long Term Employee With Some Performance Issues Show appreciation. (âWe value your stability and reliability.â) Ask how the employee thinks things are going. His/her responses may help you decide how to proceed. Remember to focus on performance, not the person. Give specific examples illustrating how the employeeâs performance did not meet your expectations.
The Law of Cosines (also called the Cosine Rule) is very useful for solving triangles: It works for any triangle: a, b and c are sides.
The cosine of a real number t is the x-coordinate of the point P in the following diagram, where | t | is the length of the arc shown. cos t = x-coordinate of the point P sin t = y-coordinate of the point P Graph of the Cosine Function. y = cos x. General Cosine Function. The generalized sine function has the following form: y = A cos[Ï(x - Î±)] + C. 1  A is the amplitude (the height of each peak above the baseline). 2  C is the vertical offset (height of the baseline). 3  P is the period or wavelength (the length of each cycle).
