For the graph of secant, we remember the reciprocal identity where . Notice that the function is undefined when the cosine is 0, leading to a vertical asymptote in the graph at π/2, 3π/2, etc. Since the cosine is always no more than one in absolute value, the secant, being the reciprocal, will always be no less than one in absolute value.

sec(A) = hypotenuse/adjacent (secant) cot(A) = adjacent/opposite (cotangent) You may have noticed that the last three ratios listed are the reciprocals, respectively, of the first three. Here is a mnemonic that may help you remember which ratio is which: SOH CAH TOA. Example. Find the cosine, tangent, and cosecant of the indicated angle:

The cosine, sine and tangent ratios are defined in terms of the lengths of the sides of a right triangle. Three other ratios are the . secant, the . cosecant. and the . cotangent. ratios. The ratios are abbreviated as sec, csc, cot. sec A = csc A = cot A = The secant ratio for A is the reciprocal of its _____ratio.

For secant a period starts with a “u” and ends with a “u” half way between is the opposite “u” and have way between the “u”s are vertical asymptotes (relates to starts at a max ends at a max, half way between is a min, half way between max and min are the x-intercepts of a cosine function).

In this lesson we will derive trigonometric ratios for sine, cosine and tangent. Definitions will be given for cosecant, secant and cotangent. Definition: If we consider angle ABC (labeled ), we can define the hypotenuse to be side BC, the adjacent side (next to angle ) to be side AB and the opposite side (opposite the angle ) to be side AC.
