Cosecant, Secant & Cotangent. mc-TY-cosecseccot-2009-1. In this unit we explain what is meant by the three trigonometric ratios cosecant, secant and cotangent. We see how they can appear in trigonometric identities and in the solution of trigonometrical equations. Finally, we obtain graphs of the functions cosec θ, sec θ and cot θ from.

•One cycle occurs between and . • There are vertical asymptotes at each end of the cycle. The asymptote that occurs at repeats every π units. • period: π • amplitude: none, graphs go on forever in vertical directions. Note: a graphing utility (such as the one used to produce these graphs) may not show the function approaching infinity (going on forever upward or downward).

Use the reciprocal relationship of the cosine and secant functions to draw the cosecant function. Steps 6-7. Sketch two asymptotes at x = 1.25π and x = 3.75π. We can use two reference points, the local minimum at (0, 2.5) and the local maximum at (2.5π, − 2.5).
Secant cosecant cotangent Explanation & Examples
Basis of trigonometry: if two right triangles have equal acute angles, they are similar, so their corresponding side lengths are proportional.. In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

Right Triangle Definitions of Cosecant, Secant, and Cotangent Math
The cosecant ( ), secant ( ) and cotangent ( ) functions are 'convenience' functions, just the reciprocals of (that is 1 divided by) the sine, cosine and tangent. So. Notice that cosecant is the reciprocal of sine, while from the name you might expect it to be the reciprocal of cosine! Everything that can be done with these convenience.
Secant cosecant cotangent Explanation & Examples
Cotangent is the reciprocal trig function of tangent function and can be defined as cot θ = cos θ /sin θ. It is an odd function, meaning cot (− θ) = − cot (θ), and it has the property that cot (θ + π) = cot (θ). Because sine is the denominator, and the function is undefined when sin (θ) = 0, the cotangent graph has vertical.
Reciprocal Trigonometric Functions (Cosecant, Secant, Cotangent) YouTube
We can do this using the Pythagorean Theorem: 52 + 122 = H2 25 + 144 = H2 169 = H2 H = 13. Now we can find the secant, cosecant, and cotangent of angle B: secB = hypotenuse adjacent side = 13 12 cscB = hypotenuse opposite side = 13 5 cotB = adjacent side opposite side = 12 5. 2. Find the secant, cosecant, and cotangent of angle A.
Philfour Precalculus Secant, Cosecant & Cotangent Introduction
The abbreviation of cosecant is csc or cosec. The cotangent function is the reciprocal of the tangent function. The abbreviation of cotangent is cot. The following diagram shows the Reciprocal Trigonometric Functions. Scroll down the page for more examples and solutions on how to use the reciprocal trigonometric functions.

Sine, Cosine and Tangent name 3 of the ratios, and the three you mentioned allow us to name all 6 ratios. Avoiding division. Example: If we know that the angle of elevation to the top of a 12 meter tall building is 40^@ and we want to find the distance to the building, call it x we could use 12/x = tan40^@ so x = 12/tan40^@ Now we get a decimal.

Secant and Cosecant. Since secant is the inverse of cosine the graphs are very closely related. Figure \(\PageIndex{1}\) Notice wherever cosine is zero, secant has a vertical asymptote and where \(\cos x=1\) then \(\sec x=1\) as well. These two logical pieces allow you to graph any secant function of the form:
