Graphing Trigonometric Functions (Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent) Flip Book This flip book reviews graphing the following trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. The secant curves will open upward along the vertical asymptotes over intervals where the secant function lies above the mid-line. Here you will extend what you know about rational functions and sine and cosine functions to produce graphs of the four other trigonometric functions: tangent, secant, cosecant, and cotangent. The three functions that we are talking about today are defined as the reciprocals of our basic three functions. Infringement Notice, it will make a good faith attempt to contact the party that made such content available by The value of r is the length of the hypotenuse of a right triangle — which is always positive and always greater than x and […] They show the domain, the input values, and the range, the output values, of these functions. 2\pi. True or False: Amplitude must be considered when graphing the transformation of a secant graph. For cosecant, graph the corresponding sine function using faded or dashed lines, for secant, use the corresponding cosine function. Please be advised that you will be liable for damages (including costs and attorneys’ fees) if you materially And then we are left with the graph of  . Thus, if you are not sure content located because secant graphs extend infinitely upwards and downwards and does not have an amplitude, we must think of the secant graph being a reciprocal of the cosine graph. Stony Brook University, Bachelor of Science, Mathematics. With the help of the community we can continue to This will be true for all transformed secant graphs as well. sufficient detail to permit Varsity Tutors to find and positively identify that content; for example we require ¤Ñ împ This will give us a phase shift of  units to the left. This shortens our original period of  to . 2π. In this section, we present to you the trigonometric graphs of the three derived trigonometric functions sec x, cosec x, cot x. Remember our basic three trigonometric functions are sine, cosine, and tangent. This is because the functions are reciprocals. Now anywhere this graph crosses the x-axis a vertical asymptote will form for the  graph because the denominator of  will be equal to zero and the function will be undefined. However, secant is the reciprocal of cosine graphs which do rely on amplitude for transformations. Also notice, that when cosine is 1, secant is al… Graphing Cosecant and Secant To graph or : 1. Varsity Tutors. Reciprocal Trigonometric Functions. Tangent & Cotangent Graphs: Learn how to graph tan and cot trig functions. Graph each function using radians. because secant graphs extend infinitely upwards and downwards and does not have an amplitude, we must think of the secant graph being a reciprocal of the cosine graph. Finding these points first helps you define the rest of the graph. For secant, the graphs remain the same. Now we must consider . [B] It is the graph of y = csc(x) shifted 6 units right. Ver Calculus: Fundamental Theorem of Calculus Students will also identify the amplitude and period of each graph. Because secant is the reciprocal of cosine, any place on the cosine graph where the value is 0 creates an asymptote on the secant graph (because any fraction with 0 in the denominator is undefined). or more of your copyrights, please notify us by providing a written notice (“Infringement Notice”) containing Since cosecant is a reciprocal of sine, it uses the same general formula of the sine function with the letters corresponding to the same transformations. Notice that x-intercepts on the cosine graph correspond to asymptotes on the secant graph. Considering the general form of the cosecant transformation function , what does each letter, (A, B, C, and D) correspond to? This eliminates one answer choice. tinkitori.
