The correct question is, Why (or when) is it useful to view [math]\cos^2(x)[/math] as a composite function? In calculus, it is useful when taking the derivative of [math]f(x) = \cos^2 x[/math] to recognize that [math]f(x)[/math] is a composition of two functions whose derivatives we (presumably) already know.
In law, fraud is deliberate deception to secure unfair or unlawful gain. Fraud is both a civil wrong (i.e., a fraud victim may sue the fraud perpetrator to avoid the fraud and/or recover monetary compensation) and a criminal wrong (i.e., a fraud perpetrator may be prosecuted and imprisoned by governmental authorities).n common law jurisdictions, as a criminal offence, fraud takes many different forms, some general (e.g., theft by false pretense) and some specific to particular categories of victims or misconduct (e.g., bank fraud, insurance fraud, forgery).
While fraud itself is an independent criminal charge, it can also appear in other charges as the means used or the intent required to commit a crime. For example, identity theft charges often require that a defendant steal anotherâs personal information with the intent to defraud them.enerally, however, fraud is a felony charge with a potential sentence of six months to five years. Additional charges can be filed for each instance of fraud committed, so someone who passes several bad checks or uses a stolen credit card several times can be charged for each of those actions.
