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).
A person who is dishonest may be called a fraud. In the U.S. legal system, fraud is a specific offense with certain features.
