Why pi is not a surd?
A surd is the square root of an integer (whole number), e.g. square root of 2 is a surd. Pi is not the square root of an integer so not a surd, just an irrational number
Tan what equals 1?
45 degrees (+/- 180k degrees for any integer k) or pi/4 radians (+/- pi*k radians for any integer k).
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.
What describes the domain of y tan x where n is any integer?
x=pi/2+npi
What Is The Inverse Tangent Of 1.25?
Arctan(1.25) = (0.896 + k*pi) radians , approx, where k is an integer.
How do you find a circumference of a circle if the radius is a fraction?
The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.
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?
A surd is the square root of an integer (whole number), e.g. square root of 2 is a surd. Pi is not the square root of an integer so not a surd, just an irrational number
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?
-1.5, -pi, -2/5
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.

Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.
What is an irrational number but not an integer?
No irrational numbers are integers. Pi is one example.
