Can numbers be undefined?

Can numbers be undefined?

We learned that a numerical expression is undefined when there is no answer or when you get division by zero. We might get division by zero for those numerical expressions with variables and a denominator. To find the points where the numerical expression is undefined, we set the denominator equal to zero and solve.

What number would undefined be?

We can say that zero over zero equals “undefined.” And of course, last but not least, that we’re a lot of times faced with, is 1 divided by zero, which is still undefined.

Is 0 same as undefined?

It is a rule that anything decided by zero is an undefined value since nothing can be divided by zero. 1.An undefined slope is characterized by a vertical line while a zero slope has a horizontal line. 2. The undefined slope has a zero as the denominator while the zero slope has a difference of zero as a numerator.

Is 0 under a number undefined?

In general, a single value can’t be assigned to a fraction where the denominator is 0 so the value remains undefined.

What are undefined terms?

Undefined Terms. In geometry, point, line, and plane are considered undefined terms because they are only explained using examples and descriptions. Name the points, Lines, & Planes. Collinear points are points. that lie on the same line.

Why undefined is false?

3 Answers. In javascript strict mode, undefined is not false, but javascript try to convert the object or var to a boolean value (this is called in javascript truthy value), that’s the reason you got an undefined as false. This happens with null also, for example.

What are the 4 undefined terms in geometry?

Undefined terms are those terms that don’t require a formal definition. The four terms are point, line, plane, and set. A point is quite simply, a dot. Points are labeled with one capital letter.

An expression in mathematics which does not have meaning and so which is not assigned an interpretation. For example, division by zero is undefined in the field of real numbers.

When is an equation undefined?

Whenever the slope (m) is undefined it means that when you try to calculate the slope given any 2 points on the line you’ll end up with a zero in the denominator, which is undefined. That is, with an undefined slope you end up with a vertical line, which has the equation “x=some number”.

When is an answer undefined?

Answer Wiki. 1 Answer. It is when an equation has no solution, or no roots. In the equation ax^2+bx+c=0, the solution is undefined when the discriminant (b^2)-4ac is less than 0, because there is no negative square root for real numbers.

When is a rational expression undefined or zero?

A rational expression is undefined when the denominator is equal to zero. To find the values that make a rational expression undefined, set the denominator equal to zero and solve the resulting equation. Example: 0 7 2 3 x x − Is undefined because the zero is in the denominator.

What is an undefined equation?

An undefined line has no equation. If it had an equation, it would be defined. You can give an equation for a class of line, e.g. ax+by+c=0 is an equation for any straight line in the x-y plane. If the gradient is undefined, the line is the y-axis, or anything parallel, where x is a constant.
