Which statement correctly defines the trigonometric ratio?

-The cotangent function is defined as the length of the side adjacent over the length of the side opposite.

-The sine function is defined as the length of the hypotenuse over the length of the side opposite.

-The cosine of an angle is defined as the length of the side opposite over the length of the side adjacent.

-The cosecant of an angle is defined as the length of the side adjacent over the length of the side opposite.

Which statement correctly defines the trigonometric ratio in the unit circle?

Hello Guest!

1.

The cotangent function of an angle  is defined as the length of the segment on the tangent above the unit circle to the radius vector.

2.

The sine function of an angle is defined as the length of the vertical distance from the intersection of the radius vector with the unit circle to the abscissa axis.

3.

The cosine function of an angle is defined as
the projection of the radius vector within the unit circle on the ascissa axis.

4.

The cosekant function of an angle is defined as the length of the radius vector up to the point of intersection with the tangent above the unit circle.
