| 单词 | cotangent |
| 例句 | Then, we can find the other trigonometric functions easily because we know that the reciprocal of sine is cosecant, the reciprocal of cosine is secant, and the reciprocal of tangent is cotangent. Precalculus 2021-12-01T00:00:00Z Tangent and cotangent have a period of What does this tell us about the output of these functions? Algebra and Trigonometry 2015-02-13T00:00:00Z The secant is the reciprocal of the cosine function, the cotangent is the reciprocal of the tangent function, and the cosecant is the reciprocal of the sine function. Algebra and Trigonometry 2015-02-13T00:00:00Z Cosine and secant are even; sine, tangent, cosecant, and cotangent are odd. Algebra and Trigonometry 2015-02-13T00:00:00Z Where the graph of the tangent function increases, the graph of the cotangent function decreases. Algebra and Trigonometry 2015-02-13T00:00:00Z The cotangent graph has vertical asymptotes at each value of where we show these in the graph below with dashed lines. Algebra and Trigonometry 2015-02-13T00:00:00Z And for tangent and cotangent, only a half a revolution will result in the same outputs. Algebra and Trigonometry 2015-02-13T00:00:00Z The cotangent identity, also follows from the sine and cosine identities. Algebra and Trigonometry 2015-02-13T00:00:00Z In quadrant III, “Trig,” only tangent and its reciprocal function, cotangent, are positive. Algebra and Trigonometry 2015-02-13T00:00:00Z Where the graph of the tangent function decreases, the graph of the cotangent function increases. Algebra and Trigonometry 2015-02-13T00:00:00Z We can interpret the cotangent of a negative angle as Cotangent is therefore an odd function, which means that for all in the domain of the cotangent function. Algebra and Trigonometry 2015-02-13T00:00:00Z The secant, cotangent, and cosecant are all reciprocals of other functions. Algebra and Trigonometry 2015-02-13T00:00:00Z |
