The Cosine function ( cos (x) ) The cosine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the adjacent side to the hypotenuse. Because the cosine is never more than 1 in absolute value, the secant, being the reciprocal, will never be less than 1 in absolute value. Sine (7π/6) - The sine function evaluates to -1/2 at 7π/6 radians, so this expression is equal to -1/2. The cot of 120 degrees equals the x-coordinate (-0. csc (90° + θ) = sec θ.
