pi is not a integer any of the natural numbers (positive or negative) or zero; "an integer is a number that is not a fraction"- since pi has a decimal it isn't considered a integer

What is pi times pi to the nearest integer?

π 2 = π x π = approx. 9.86, the nearest integer is 10.


Is pi a composite number?

No. The concept of composite is applicable to integers. Pi is not an integer.


What times pi is a whole number?

If n is any integer, then (n/pi) times pi is a whole number.


Why pi is not a surd?

'pi' is not a 'surd' because it is not a 'square root' of any number. 'pi' is an IRRATIONAL number. Irrational numbers are those were the decimals go to infinity AND the decinal digits are not in any regular order. pi = 3.141592654.... (recur to infinity and no regular order0. 'pi' in surd form is sqrt(pi) = sqrt(3.141592654....) = 1.772453851..... (which is also irrational). In school/college etc., you are given 'pi = 3.14 , 3.1416 , 22/7' Tese are only APPROXIMATIONS for ease of calculating. 'Super Dupa' computers have calculated 'pi' to at least 50 billion places and still going. NB A decimal number such as 1.33333.... is NOT irrational. It is RATIONAL , because it can be converted to a ration/quotient/fraction. Irrational numbers cannot be converted to an exact value 'ratio/quotient/fraction'. Notice the decimal digits are in a regular order of '3'....


What is the measurement for which the sine is at its maximum?

It is pi/2 + 2*k*pi radians for integer k.


What are some examples of a fraction but not a rational number?

A rational number is a fraction with an integer in the numerator, and a non-zero integer in the denominator. If you consider pi/2, pi/3, pi/4 (common 'fractions' of pi used in trigonometry) to be 'fractions', then these are not rational numbers.


What number that is a negative but not integer?

Tan what equals 1?

45 degrees (+/- 180k degrees for any integer k) or pi/4 radians (+/- pi*k radians for any integer k).


When cosec is positive?

Between (2k)*pi radians and (1+2k)*pi radians where k is an integer. If you are still working with degrees, that is360*k degrees to (1+2k)*180 degrees, for integer values of k.NB: these are open intervals: that is, the end points are not included.Between (2k)*pi radians and (1+2k)*pi radians where k is an integer.

How do you Solve cos2 x equals 1?

To solve the equation (\cos(2x) = 1), we recognize that (\cos(\theta) = 1) at integer multiples of (2\pi). Therefore, setting (2x = 2k\pi) for any integer (k), we can solve for (x) by dividing both sides by 2, yielding (x = k\pi). Thus, the general solution is (x = k\pi), where (k) is any integer.


Can the quotient of two irrational numbers be rational?

Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.
