Trigonometry The classic 30° triangle has a hypotenuse of length 2, an opposite side of length 1 and an adjacent side of√ 3: now we know the lengths, we can calculate the functions: sine. sin (30°) = 1 2 = 0.5. cosine. cos (30°) = 1.732 2 = 0.866 tangent. tan (30°) = 1 1.732 = 0.577 (get your calculator out and check them!). Sine, cosine and tangent. and sine, cosine and tangent are the three main functions in trigonometry they are often shortened to sin, cos and tan the calculation is simply one side of a right angled triangle divided by another side we just have to know which sides, and that is where "sohcahtoa" helps.
Sine Cosine Tangent The first one is a reciprocal: csc θ = 1 sin θ. \displaystyle \csc {\ }\theta=\frac {1} { { \sin {\ }\theta}} csc θ = sin θ1 . . the second one involves finding an angle whose sine is θ. so on your calculator, don't use your sin 1 button to find csc θ. we will meet the idea of sin 1θ in the next section, values of trigonometric. Range of values of sine. for those comfortable in "math speak", the domain and range of sine is as follows. domain of sine = all real numbers; range of sine = { 1 ≤ y ≤ 1} the sine of an angle has a range of values from 1 to 1 inclusive. below is a table of values illustrating some key sine values that span the entire range of values. Other functions (cotangent, secant, cosecant) similar to sine, cosine and tangent, there are three other trigonometric functions which are made by dividing one side by another: cosecant function: csc (θ) = hypotenuse opposite. secant function: sec (θ) = hypotenuse adjacent. cotangent function: cot (θ) = adjacent opposite. The sin cos tan formulas can be remembered using soh cah toa. it means that sine is opposite over the hypotenuse, cosine is adjacent over hypotenuse, and tan is opposite over adjacent. what are the applications of sin cos tan formulas? the sin cos tan formulas are mainly used in finding the unknown lengths of a right angled triangle.
Sine Cosine Tangent Other functions (cotangent, secant, cosecant) similar to sine, cosine and tangent, there are three other trigonometric functions which are made by dividing one side by another: cosecant function: csc (θ) = hypotenuse opposite. secant function: sec (θ) = hypotenuse adjacent. cotangent function: cot (θ) = adjacent opposite. The sin cos tan formulas can be remembered using soh cah toa. it means that sine is opposite over the hypotenuse, cosine is adjacent over hypotenuse, and tan is opposite over adjacent. what are the applications of sin cos tan formulas? the sin cos tan formulas are mainly used in finding the unknown lengths of a right angled triangle. The trigonometric functions are defined based on the ratios of two sides of the right triangle. there are six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. these functions are often abbreviated as sin, cos, tan, csc, sec, and cot. their definitions are shown below. sine, cosine, and tangent are the three most. Given the side lengths of a right triangle and one of the acute angles, find the sine, cosine, and tangent of that angle. find the sine as the ratio of the opposite side to the hypotenuse. find the cosine as the ratio of the adjacent side to the hypotenuse. find the tangent as the ratio of the opposite side to the adjacent side.
