Sin Cos Tan Definitions Facts And Solved Examples Cuemath Examples on sin cos tan. example 1: find value of cos θ with respect to the triangle, such that the sides opposite and adjacent to θ measure 6 units and 8 units respectively. solution: to find cos θ, we need the adjacent side and the hypotenuse. here, the adjacent side = 8. but we are not given the hypotenuse. Let us see the applications of the sin cos tan formulas in the section below. examples using sin cos tan formulas. example 1: using the triangle below, find the value of sin a, cos a, and tan a. using sin cos tan formulas solution: using sin cos tan formulas, sin a = side opposite to angle a hypotenuse = bc ab = 5 13.
Sin Cos Tan Formulas What Are Sin Cos Tan Formulas Examplesођ The trigonometric functions have values of θ, (90° θ) in the first quadrant. the cofunction identities provide the interrelationship between the different complementary trigonometric functions for the angle (90° θ). sin (90°−θ) = cos θ. cos (90°−θ) = sin θ. tan (90°−θ) = cot θ. cot (90°−θ) = tan θ. Solved examples on trigonometric functions. example 1: find the values of sin 45°, cos 60° and tan 60°. solution: using the trigonometric table, we have. sin 45° = 1 √2. cos 60° = 1 2. tan 60° = √3. example 2: evaluate sin 105° degrees. solution: sin 105° can be written as sin (60° 45°) which is similar to sin (a b). The six trigonometric functions are sine, cosine, secant, cosecant, tangent and cotangent. by using a right angled triangle as a reference, the trigonometric functions and identities are derived: sin θ = opposite side hypotenuse. cos θ = adjacent side hypotenuse. tan θ = opposite side adjacent side. You can also see graphs of sine, cosine and tangent. and play with a spring that makes a sine wave. less common functions. to complete the picture, there are 3 other functions where we divide one side by another, but they are not so commonly used. they are equal to 1 divided by cos, 1 divided by sin, and 1 divided by tan:.

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. 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.
