Primary or focal hyperhidrosis may be further divided by the area affected, for instance palmoplantar hyperhidrosis (symptomatic sweating of only the hands or feet) or gustatory hyperhidrosis (sweating of the face or chest a few moments after eating certain foods).
The proverb The proof of the pudding is in the eating dates back to at least the 14th century. 1  The phrase is widely attributed to the Spanish author Cervantes in his novel The Ingenious Gentleman Don Quixote. The phrase is often incorrectly stated as the proof is in the pudding..
In mathematics, a proof is a deductive argument for a mathematical statement. In the argument, other previously established statements, such as theorems, can be used. In principle, a proof can be traced back to self-evident or assumed statements, known as axioms.n proof by contradiction (also known as reductio ad absurdum, Latin for by reduction to the absurd), it is shown that if some statement were true, a logical contradiction occurs, hence the statement must be false.
