If we construct a triangle in a circle of radius

, the radius of the circle will be the hypotenuse of our triangle, and the legs will be

and

as you can see in the picture.
Now we can construct our trigonometric ratios for our triangle as usual:
$sin \alpha = \frac{y}{r}$
$cos \beta = \frac{x}{r}$
$tan \beta = \frac{y}{x}$
$csc \beta = \frac{r}{y}$
$sec \beta = \frac{r}{x}$
$cot \beta = \frac{x}{y}$

As you can see the only two trigonometric functions that don't depend on the value of

are tangent and cotangent.
Which of the six trigonometric functions do not depend on the value of r?
