Domain of f(x) is the range of f⁻¹(x)
f(g(x))=x
g(f(x))=x
If f(x) passes the horizontal line test, then its inverse is a function.
if f(x) does not pass the vertical line test, then its inverse is not a function.

# data[].attributes.body
It is only a function if a Domain has only one Range. A Range can have more than one Domain though.

Sine: OPP/HYP - In the Unit Circle, it corresponds to the y-coordinate.

Cosine: ADJ/HYP - In the Unit Circle, it corresponds to the x-coordinate

Tangent: OPP/ADJ - It is the slope of the hypotenuse since it would be the sin(x)/ cos(x)

Cosecant: HYP/OPP - The reciprocal of sine

Secant: HYP/ADJ - The reciprocal of cosine

Cotangent: ADJ/OPP - The reciprocal of tangent
