In a right triangle, the trigonometric functions are: sine θ =opposite/hypothenusecosine θ =adjacent/hypothenusetangent θ =opposite/adjacent trig·o·no·met·ric function (trĭg′ə-nə-mĕt′rĭk) A function of an angle, as the sine, cosine, or tangent, whose value is express...
In this context, one might wonder: what is the cosine function? Or what is the cosine definition, that is, what is the cos meaning? It turns out that right triangles are useful for providing the trigonometric ratios of acute angles, that is, angles between {eq}0^{\circ} {/eq} and ...
One of the interesting properties of the cosine function (and of the trigonometric functions in general) is its periodicity. A functionfis said to be periodic if there exists a real number not equal to zero, say,p, such thatf(x+p)=f(x)for everyxin the domain off. The smallest positive...

The meaning of COFUNCTION is a trigonometric function whose value for the complement of an angle is equal to the value of a given trigonometric function of the angle itself. How to use cofunction in a sentence.
the sine is thex-coordinate of the point where the line intersects the circle. WhenAis expressed in radians, the cosine function has a period of 2π. The function has amaximumvalue of 1 at 0 and aminimumof −1 at π; it has a value of 0 at π/2 and 3π/2. Also, cos (−...
The meaning of COSINE is a trigonometric function that for an acute angle is the ratio between the leg adjacent to the angle when it is considered part of a right triangle and the hypotenuse.
Trigonometric function, in mathematics, one of six functions (sine, cosine, tangent, cotangent, secant, and cosecant) that represent ratios of sides of right triangles. It can be used in problems in which a right triangle’s acute angle and length of one
