## What is the antiderivative of zero? Zero doesn’t have a multiplicative inverse as multiplicative inverse is the reciprocal for a number “a”, denoted by 1/a, is a number which when multiplied by “a” yields the multiplicative identity 1. The product of any real number with zero is zero.

## Is zero less than or equal to zero?

• No zero is not less then zero, i <= 0 becomes 1 because zero is less than or equal to zero. Of course zero isn't less than zero, but i <= 0 becomes 1 because zero is less than or equal to zero. The variable type of i is never mentioned. If it is unsigned i then the < 0 part of the test will fail.

## Does zero divided by zero equal zero?

• ZERO DIVIDED by zero is quite indeterminate. For if A is B times C, then A divided by B is C. But zero is equal to zero times any number whatever. Therefore zero divided by zero is any number whatever. Ivor Etherington, Easdale, Argyll.

## What is the inverse tangent of zero?

• The answer is –45°. With inverse tangent, we select the angle on the right half of the unit circle having measure as close to zero as possible. Thus tan-1 (–1) = –45° or tan-1 (–1) = –π/4. In other words, the range of tan-1 is restricted to (–90°, 90°) or .

The derivative of a constant function is the zero function. Therefore, any constant function is an antiderivative of the zero function. If U {\displaystyle U} is a connected set, then the constant functions are the only antiderivatives of the zero function.
