## What is the base value of the natural logarithm?

Napier's constant. The natural logarithm of a number is its logarithm to the base of the mathematical constant e (Euler's number), occasionally referred to as Napier's constant. The common logarithm is the logarithm with base 10, while the binary logarithm is the logarithm with base 2.

## Which quadric surface is shaped like a saddle?

Hyperbolic paraboloid. The widely sold fried snack food Pringles potato chips resemble a truncated hyperbolic paraboloid. The distinctive shape of these chips allows them to be stacked in sturdy tubular containers, fulfilling a design goal that they break less easily than other types of chip.

## In math; Estimating the value of a function at a point outside the range in which the data is ?

Interpolation. In engineering and science, one often has a number of data points, obtained by experimentation, which represent the values of a function for a limited number of values of the independent variable. It is often required to interpolate (i.e., estimate) the value of that function for an intermediate value of the independent variable.

## What is this symbol $\int$ called?

Is an elongated letter S, from the Latin "summa" (sum). The notation was introduced by the German mathematician Gottfried Wilhelm Leibniz in 1675 in his private writings; The symbol was based on the ſ (long s) character, and was chosen because Leibniz thought of the integral as an infinite sum of infinitesimal summands.

## A given natural number is divisible by 4 if and only if ...?

The number created from the last two digits is divisible by 4. The last two digits form a number that is divisible by 4; 40,832: 32 is divisible by 4. If the tens digit is even, the ones digit must be 0, 4, or 8. If the tens digit is odd, the ones digit must be 2 or 6. 40,832: 3 is odd, and the last digit is 2. Twice the tens digit, plus the ones digit is divisible by 4.
