There are six trigonometry ratios. The three basic trigonometric ratios are sine, cosine, and tangent. The other three ratios are derived from the above three mentioned ratios. They are cosecant, secant, and cotangent which are the reciprocals of sine, cosine and tangent. The ratios of six important trigonometric functions are: Sine (sin) = Opposite side/ Hypotenuse Cosine (cos) = Adjacentside/ Hypotenuse Tangent (tan)= Opposite side/ Adjacent Cosecant (csc) = Hypotenuse/Opposite Side Secant (sec) = Hypotenuse / Adjacent Side Cotangent (cot) = Adajcent Side/ Opposite Side Right triangle calculatorEnter one side and second value and press the Calculate button: Side a Side b Side c Angle A Angle B Trigonometric functions calculatorTriginometric expression calculatorExpression with sin(angle deg|rad)/cos(angle deg|rad)/tan(angle deg|rad)/asin()/acos()/atan(): Expression Result Trigonometric functionssin A = opposite / hypotenuse = a / c cos A = adjacent / hypotenuse = b / c tan A = opposite / adjacent = a / b csc A = hypotenuse / opposite = c / a sec A = hypotenuse / adjacent = c / b cot A = adjacent / opposite = b / a See also
Trigonometric Functions TutorialThe six trigonometric functions are sin, cos, tan, csc, sec, and cot. These trig functions allow you to find missing sides of triangles. Trig functions are ratios in a right triangle relative to an angle. Sin of an angle is the ratio of the side length opposite to the angle to the hypotenuse length. Cos of an angle is the ratio of the side length adjacent to the angle to the hypotenuse length. Tan is the ratio of the opposite side length to the adjacent side length. Csc is the reciprocal of sin or the ratio of the hypotenuse to the opposite side instead of the opposite side to the hypotenuse. Sec is the reciprocal of cos or the ratio of the hypotenuse to the adjacent side. Cot is the reciprocal of tan or the ratio of the adjacent side to the opposite side. The way these trig functions are used to find missing sides in a right triangle is shown in the example below. If a right triangle has an angle or measure 27 degrees and a hypotenuse of length 88. The sin function will allow you to find the opposite side length of the triangle. The calculation process for this is shown below. \sin (\text{angleA})=\frac{\text{opposite}}{\text{hypotenuse}} \sin (\text{angleA})=\frac{(\text{sideA})}{(\text{sideC})} \sin ((27))=\frac{\text{sideA}}{(88)} \text{sideA}=\sin (27)\cdot 88 \text{sideA}=39.9511639770801177 Once the opposite side length is known, the cos function can be used to find the adjacent side length of the triangle. The calculation process for this is shown below: \cos (\text{angleA})=\frac{(\text{sideB})}{(\text{sideC})} \cos ((27))=\frac{\text{sideB}}{(88)} \text{sideB}=\cos (27)\cdot 88 \text{sideB}=88\cos (27) \text{sideB}=78.4085741285763719 Given only two sides of a right triangle it is also possible to find any angles in a right triangle. If given sides only, inverse trigonometric functions must be used to find the angle measures. The inverse trig functions are arcsin, arccos, arctan, arccsc, arcsec, and arccot. The example below demonstrates the process involved in calculating angle measures given two side lengths of a right triangle. If the hypotenuse of a triangle is of length 34 and the side length adjacent to an unknown angle has length 14, the calculation process shown below can be used. \cos (\text{angleA})=\frac{\text{adjacent}}{\text{hypotenuse}} \cos (\text{angleA})=\frac{\text{sideB}}{\text{sideC}} \cos (\text{angleA})=\frac{(14)}{(34)} \text{angleA}=\cos ^{-1}(\frac{14}{34}) \text{angleA}=65.684260828823524^\circ What are the 6 trigonometric functions calculator?Underneath the calculator, six most popular trig functions will appear - three basic ones: sine, cosine and tangent, and their reciprocals: cosecant, secant and cotangent.
What are the six trigonometric functions of θ?Thus, for each θ, the six ratios are uniquely determined and hence are functions of θ. They are called the trigonometric functions and are designated as the sine, cosine, tangent, cotangent, secant, and cosecant functions, abbreviated sin, cos, tan, cot, sec, and csc, respectively.
What is the value of angle θ?The sine of the angle θ is represented by the y-value of the point P on the unit circle. Thus, since sin θ = sin (180 − θ), we mark the two equal intervals in the graph. Hence, between 0° and 180°, the graph is symmetric about θ = 90°. Similarly, between 180° and 360°, the graph is symmetric about θ = 270°.
