Prove

1,000+ companies, including 8 out of 10 top banks trust Prove As the world moves to a digital-first economy, businesses need to modernize how they acquire, engage with, and enable consumers. Prove enables businesses to improve consumer experience, mitigate fraud, and rapidly grow with the world’s most frictionless and accurate identity verification & authentication solutions. "Prove's solutions significantly simplify the enrollment processes for millions of Zelle P2P users while adding another layer of non-intrusive protection behind-the-scenes for Zelle. Prove brings together data from across the mobile ecosystem—networks, devices, users—to help us assess enrollment and transaction risk almost instantly. This helps us balance the requirements for speed and security in the faster payments space." "At Binance.US, our goal is to democratize access to digital asset ownership and facilitate simple and safe participation in cryptocurrency markets for all Americans. We selected Prove to help us achieve this goal after a rigorous evaluation and proof-of-concept test demonstrating Prove’s pass rates and ability to deliver seamless customer experiences." "We've integrated Prove Pre-Fill ®, and it's a phenomenal solution that drives real results. It not only increases the completion rate and helps you increase sales, but it really does all the fraud work in the background, so it doesn't impact the customer experience, AND we saw a significant decrease in the fraud rate. We've had am...

3.4: Using Cases in Proofs

\( \newcommand\) • • • • • • • • • • • • • • PREVIEW ACTIVITY \(\PageIndex\): Using a Logical Equivalency • Complete a truth table to show that \((P \vee Q) \to R\) is logical equivalent to \((P \to R) \wedge (Q \to R)\). • Suppose that you are trying to prove a statement that is written in the form \((P \vee Q) \to R\). Explain why you can complete this proof by writing separate and independent proofs of \(P \to R\) and \(Q \to R\). • Now consider the following proposition: Proposition. For all integers \(x\) and \(y\), if \(xy\) is odd, then \(x\) is odd and \(y\) is odd. Write the contrapositive of this proposition. • Now prove that if \(x\) is an even integer, then \(xy\) is an even integer. Also, prove that if \(y\) is an even integer, then \(xy\) is an even integer. • Use the results proved in part (4) and the explanation in part (2) to explain why we have proved the contrapositive of the proposition in part (3). Preview Activity \(\PageIndex\) was meant to introduce the idea of using cases in a proof. The method of using cases is often used when the hypothesis of the proposition is a disjunction. This is justified by the logical equivalency \[[(P \vee Q) \to R] \equiv [(P \to R) \wedge (Q \to R)]\] See Theorem 2.8 on page 48 and Exercise (6) on page 50. In some other situations when we are trying to prove a proposition or a theorem about an element \(x\) in some set \(U\), we often run into the problem that there does not seem to be enough information about x to pro...
