It is the ratio of cosine and sine function
To define the sine and cosine of an acute angle α, start with a right triangle that contains an angle of measure α; in the accompanying figure, angle α in triangle ABC is the angle of interest. The three sides of the triangle are named as follows: • The opposite side is the side opposite to the angle of interest, in this case sid… WebThe cosine function is one of the basic functions encountered in trigonometry (the others being the cosecant, cotangent, secant, sine, and tangent). Let be an angle measured counterclockwise from the x-axis …

Proof using the … WebThe sum of two cosine functions can be described by the rule: "the sum of the cosines is equal to two times the cosine of the half‐difference multiplied by the cosine of the half‐sum." A similar rule is valid for the difference of …
WebExplained Visually. Sine and cosine — a.k.a., sin (θ) and cos (θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin (θ) is the ratio of the opposite side to the hypotenuse, while cos (θ) is the ratio of the adjacent side to the hypotenuse. No matter the size of the triangle, the values ... WebTrigonometric Ratios. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
