In the right triangle, the proportion regarding the length of along side it adjacent to an acute perspective to your length of the hypotenuse.

The abscissa at endpoint of an arc of a unit circle centered in the beginning of a Cartesian coordinate system, the arc being of length x and sized counterclockwise from point (1, 0) if x is positive or clockwise if x is unfavorable.

In the right triangle, the proportion of period of the medial side next to an acute angle into length of the hypotenuse. Logo: cos

The sine of the complement of an arc or direction. See Illust. of features.

In trigonom., the sine associated with the complement of confirmed angle (whoever cosine it is).

proportion of the adjacent part on hypotenuse of a right-angled triangle

In a right triangle, the proportion of this period of the medial side next to an acute angle into the length of the hypotenuse.

The abscissa at endpoint of an arc of a unit circle focused at the source of a Cartesian coordinate system, the arc being of length x and measured counterclockwise from the point (1, 0) if x is positive or clockwise if x is negative.

In a right triangle, the ratio associated with the amount of along side it right beside an acute perspective toward duration of the hypotenuse. Expression: cos

The sine of the complement of an arc or direction. See Illust. of functions.

In trigonom., the sine regarding the complement of certain angle (whoever cosine it really is).

proportion of adjacent part to your hypotenuse of a right-angled triangle
