Solution Scanning Code39 In .NET Using Barcode Control SDK for .NET Control to generate, create, read, scan barcode image in .NET framework applications. Encoding ANSI/AIM Code 39 In Visual Studio .NET Using Barcode creation for .NET framework Control to generate, create Code 39 Extended image in Visual Studio .NET applications. We can simplify this problem by remembering a few basic facts in trigonometry, and by applying a little algebra First, let s remember that the cosecant is equal to the reciprocal of the sine, so the converse is also true We have 1/(csc q) = sin q When we square both sides, we get 1/(csc2 q) = sin2 q Substituting in the equation for our function gives us f (q) = (sec2 q) (sin2 q) We ve learned that the secant is equal to the reciprocal of the cosine We have sec q = 1/(cos q) so we can square both sides to get sec2 q = 1/(cos2 q) Decoding Code 39 In Visual Studio .NET Using Barcode decoder for Visual Studio .NET Control to read, scan read, scan image in .NET framework applications.

Code 3 Of 9 Creation In C#.NET Using Barcode generator for Visual Studio .NET Control to generate, create ANSI/AIM Code 39 image in .NET framework applications. Substituting again in the equation for our original function, we obtain f (q) = (sin2 q)/(cos2 q) = [(sin q)/(cos q)]2 The sine over the cosine is equal to the tangent, so we can substitute again to conclude that our original function is f (q) = tan2 q with the restriction that we can t define it for any input value where either the secant or the cosecant become singular The solid black curves in Fig 1510 show the result of squaring all the values of the tangent function, noting the additional undefined values as open circles At the points shown by the open circles, the cosecant function is singular so its square is undefined That means we can t define our ratio function f at any such point At the asymptotes (dashed vertical lines), the secant function is singular so its square is undefined, making it impossible to define the ratio function f for those values of q Our function f has a period of p The domain of f includes all real numbers except integer multiples of p /2, where one or the other of the original squared functions is singular The range is the set of all positive reals Code39 Encoder In .NET Framework Using Barcode generator for ASP.NET Control to generate, create ANSI/AIM Code 39 image in ASP.NET applications.

You were introduced to graphs of the basic tangent and cotangent functions in Chap 2 The tangent is the ratio of the sine to the cosine, and the cotangent is the ratio of the cosine to the sine Now we ll see what happens when we alter or combine these functions in a few different ways Tangent and cotangent: example 1 In Fig 1511, the dashed gray curves are superimposed graphs of the tangent and cotangent functions The solid black curves portray the graph of f (q) = tan q + cot q The graph of f has asymptotes that pass through every point where the independent variable attains an integer multiple of p /2 The period is p The domain is the set of all real numbers except the integer multiples of p /2 The range is the set of reals larger than or equal f (q ) Each horizontal division is p /2 units Each vertical division is 1 unit

to 2 or smaller than or equal to 2 We can also say that the range spans the set of all reals except those in the open interval ( 2,2) Tangent and cotangent: example 2 Figure 1512 shows superimposed graphs of the tangent and cotangent functions (dashed gray curves) along with their product (black line with holes in it) We have f (q) = tan q cot q We can simplify the calculations to graph this function when we recall that the cotangent and the tangent are reciprocals of each other, so we have cot q = 1/(tan q) This equation is valid as long as both functions are defined and tan q 0 By substitution, the equation for our function f becomes f (q) = (tan q)/(tan q) = 1 f (q )
