The squared functions have periods of p, which are half the periods of the original functions Therefore, the frequencies of the squared functions are double those of the originals Singularities occur at the same points on the independentvariable axes as they do for the original functions The domain of the secantsquared function is the set of all reals except oddinteger multiples of p/2 The domain of the cosecantsquared function is the set of all reals except integer multiples of p The ranges in both cases are confined to the set of reals y such that y 1 Barcode Generator In ObjectiveC Using Barcode encoder for iPhone Control to generate, create bar code image in iPhone applications. GTIN  12 Generator In Java Using Barcode creator for Java Control to generate, create UPC A image in Java applications. Secant and cosecant: example 4 Figure 159 shows what happens when we add the secantsquared function to the cosecantsquared function The solid black curves compose the graph of f (q) = sec2 q + csc2 q The dashed gray curves are superimposed graphs of the original functions This sum function has a period equal to half that of the original functions, or p/2 The domain includes all reals except the integer multiples of p/2 The range is the set of reals y such that y 4 Figure 159 Graph of the sum of the squares of the secant and cosecant functions (solid black curves) The dashed gray curves are the graphs of the original squared functions Each horizontal division represents p/2 units Each vertical division represents 1 unit The vertical dashed lines are asymptotes of f The positive dependentvariable axis is also an asymptote of f Each horizontal division is p /2 units

Are you confused
You re bound to wonder, How do we know that the range of the sumofsquares function in the previous example is the set of all reals greater than or equal to 4 Another way of stating this fact is that the minima of the solid black curves in Fig 159 have dependentvariable values equal to 4 These minima occur at values of q where the graphs of the secantsquared and cosecantsquared functions (dashed gray curves) intersect Every one of those points occurs where q is an oddinteger multiple of p /4 With the help of your calculator, you can determine that whenever q is an oddinteger multiple of p/4, the secant squared and cosecant squared are both 2, so their sum is 4 If you move slightly to the right or left of any of these points, the value of the sumofsquares function increases (a fact that you can, again, check out with your calculator) It follows that the sumofsquares function can never attain any realnumber value less than 4 However, there s no limit to how large the value of the function can get One or the other of the original functions blows up positively at every point where q attains an integer multiple of p /2 Here s a challenge! Sketch a graph of the ratio of the square of the secant function to the square of the cosecant function That is, graph f (q) = (sec2 q)/(csc2 q) Determine the domain and range of f Be careful! Both the domain and the range have some tricky restrictions
