Our function, f( x ) = 3 sin(4 x + 2), is a sine function, so the period . Secant (sec) Cosecant (csc) Cotangent (cot) All six functions have three-letter abbreviations (shown in parentheses above). Graph tangent and cotangent Graph tangent and cotangent The sketching and graphing of the tangent and cotangent functions of the form y = a tan [ k ( x - d) ] and y = a cot [ k ( x - d) ] are discussed with detailed examples. Graphing One Period of a Shifted Tangent Function Now that we can graph a tangent function that is stretched or compressed, we will add a vertical and/or horizontal (or phase) shift. Click here to get an answer to your question Which of the following are the same for both the tangent and cotangent functions? = 1/sinx As you can see, if secx= 1/cosx, then secx= (1/cosx) = 1/cosx, similarly, -cscx = - 1/sinx They are equivalent, either is fine. If you can remember the graphs of the sine and cosine functions, you can use the identity above (that you need to learn anyway!) There will generally be around 4-6 questions questions on the ACT that deal with trigonometry (the official ACT guidelines say that trigonometry . . And lastly tangent can be defined as cosine divided by sine, so the quotient y/x is the tangent value .

(Actually, it approaches minus infinity as t approaches /2 from the right as you can see on the graph. Sine, cosine, and tangent and their reciprocals, cosecant, secant, and cotangent are periodic functions, which means that their graphs contain a basic shape that repeats over and over indefinitely to the left and the right. Mr. Murdick demonstrates how to graph y=tan(x) and y=cot(x) from elementary considerations about the unit circle. Therefore, the domain would be (-\infty, \infty) \ \{\frac{\pi}{2} + n\pi:n . The cotangent The cotangent is the reciprocal of the tangent. Amplitude = a. As the particle moves through the four quadrants, we get four pieces of the sin graph: I. . The parent graphs of tangent and cotangent are comparable because they both have asymptotes and x- intercepts.

Tangent (tan) The other three are not used as often and can be derived from the three primary functions. Furthermore, we observe that the graph starts at the bottom and increases from left to right, consistent with tangent graphs. From 0 to 90 the y-coordinate increases from 0 to 1 II. The function with other values for the parameters appears in green. We can graph $$y=\sec x$$ by observing the graph of the cosine function because these two functions are reciprocals of one another. For the angle in a right-angled triangle as shown, we name the sides as:. . At /2 radians (90), and at /2 (90), 3 /2 (270), etc, the function is officially undefined, because it could be .

In this case, we add C and D to the general form of the tangent function. it goes between negative and positive Infinity, crossing through 0, and at every radians (180), as shown on this plot. Since the cotangent function is NOT defined for integer multiples of , there are vertical asymptotes at all multiples of in the graph of cotangent. Sine and Cosine Functions - amplitude, period, phase-shift, sinusoidal functions, periodic functions . Remember: When we use the words 'opposite' and 'adjacent,' we always have to have a specific angle in mind. So we narrow our focus to the choices involving tangents. If your trig function is either a tangent or cotangent, then you'll need to divide pi by the absolute value of your B.

If you know the unit circle, you can easily . Back to Top. Graphing Sine and Cosine. The graph of the cosine is shown as a dashed orange wave so we can see the relationship. . Graphing sine and cosine functions (and domain and range) (To me, this video is not as clear as the Khan Academy videos above) Graphs of Trig Functions (has sin, cos, and tan) Play with different values for A, b, c, d in trig functions. The only differences you can see are the values of theta where the asymptotes and x- intercepts occur. For tangent, that would be at values of x that make cos (x) = 0 --- in other words, at x = 90 degrees and at x = 270 degrees for 0 <= x <=360.
