What values of sin are rational?

For rational values of θ, the only rational values of the sine or cosine are 0, ±1/2, and ±1; the only rational values of the secant or cosecant are ±1 and ±2; and the only rational values of the tangent or cotangent are 0 and ±1.

Is a sine function rational?

What makes an equation a rational function?

A rational function is a function that is a fraction and has the property that both its numerator and denominator are polynomials. In other words, R(x) is a rational function if R(x) = p(x) / q(x) where p(x) and q(x) are both polynomials.

What is rational triangle?

Somos defines a rational triangle as a triangle such that all three sides measured relative to each other are rational. Conway and Guy (1996) define a rational triangle as a triangle all of whose sides are rational numbers and all of whose angles are rational numbers of degrees. …
