Magnitude

A vector is an element with both direction and magnitude. A vector is represented using an arrow, where the arrow represents the direction of the vector and its length is represented using the magnitude. The set of vectors in space is known as vector space. The vectors can be added, subtracted, multiplied, and divided in a vector space. The image below shows a vector AB.

Question

**Logical Statement Analysis**

The statement to evaluate is:

\[\lnot \forall x \, P(x) \text{ is equivalent to } \exists x \, \lnot P(x).\]

Determine if the following is true or false:
- ○ True
- ○ False

**Explanation:**

The expression $\lnot \forall x \, P(x)$ translates to "It is not true that for all $x$, $P(x)$ is true." This means there exists at least one $x$ for which $P(x)$ is not true. Therefore, $\lnot \forall x \, P(x)$ is logically equivalent to $\exists x \, \lnot P(x)$.

The options provided are to verify this equivalence logically.

Expert Solution

Step 1

$\neg \forall x P (x) \equiv \exists x \neg P (x)$

but it is given that $\neg \forall x P (x) \equiv \forall x \neg P (x)$
