  • Section 3.34. Trigonometric Functions 1 Section 3.34
    Section 3.34. Trigonometric Functions 1 Section 3.34. Trigonometric Functions Note. In this section we define the complex trigonometric functions and some of their properties. We also relate them to the real hyperbolic trig functions. Note. To recap, we have defined the complex exponential function in terms of the real exponentiation function, the real sine function, and the real cosine function: ez = ex+iy = ex(cos y + i sin y). We continue this trend of defining new functions in terms of existing ones. Note. Since Euler’s formula gives (for x ∈ R) eix = cos x + i sin x and e−ix = cos x − i sin x, then we can solve for cos x and sin x to get eix + e−ix eix − e−ix cos x = and sin x = . 2 2i This motivates the following definition. Definition. For all z ∈ C define the cosine and sine functions as eiz + e−iz eiz − e−iz cos z = and sin z = . 2 2i Note 3.34.A. Since ez is an entire function, then cos z and sin z are entire func- tions. Notice that the cosine and sine functions of a complex variable agree with the cosine and sine functions of a real variable when z is real. Therefore, by Theo- rem 2.27.A, cos z and sin z are the unique entire functions which agree with cos x Section 3.34. Trigonometric Functions 2 and sin x. They satisfy the expected differentiation properties: d d eiz + e−iz ieiz − ie−iz −eiz + e−iz eiz − e−iz [cos z] = = = = − = − sin z dx dz 2 2 2i 2i d d eiz − e−iz ieiz + ie−iz eiz + e−iz [sin z] = = = = cos z.

  • Pythagorean Theorem
    65 Determinant |A| To evaluate the determinant |A|, select any row (or column) of |A| and then multiply each element in the row (or column) by its own cofactor and then perform a summation of these products. This is called expansion by cofactors. For example, by selecting the first row of |A|, the determinant is obtained from the expansion n |A| = a11C11 + a12C12 + a13C13 + ···+ a1nC1n = X a1kC1k (2.47) k=1 In the special case of a 3 × 3 determinant the expansion by cofactors along the first row gives a11 a12 a13 1+1 a22 a23 1+2 a21 a23 1+3 a21 a22 |A| = a21 a22 a23 = a11(−1) +a12(−1) +a13(−1) (2.48) a32 a33 a31 a33 a31 a32 a31 a32 a33 For determinants of order n>4 the method of cofactor expansion for the evaluation of a determinant is not recommended because it is too time consuming. Evaluation of cofactors requires the evaluation of approximately n! arithmetic operations. Use instead elementary row operations to reduce the matrix of the determinant to a diagonal form. The determinant is then the product of the diagonal elements. Pythagorean Theorem Theorem Let a and b denote the legs of a right triangle and let c denote the hypotenuse, then a2 + b2 = c2. Proof: For the right triangles illustrated, show using similar b α a β triangles = and = or b2 = αc and a2 = βc and c b c a consequently by addition b2 + a2 = c(α + β)=c · c = c2 Certain special right triangles having integer values for their sides have been found in Egyptian and Babylonian documents.

  • 9.4 Inverse Hyperbolic Functions
    CHAPTER 9 Inverse Trigonometric, COPY Hyperbolic, and Inverse Hyperbolic Functions [Calculus is] the outcome of a dramatic intellectual struggle which has lasted for twenty-five hundred years... RICHARD COURANT Mathematics is the subject in which we never know what we are talking about, nor whether what we are saying is true. BERTRAND RUSSELL Do I contradict myself? Very well then I contradict myself. (I am large, I contain multitudes.) WALT WHITMAN (1819–1892) CAREERS IN CALCULUS: ARCHITECTURE In thinking about the skills needed by a good architect, most people would include drawing ability, an eye for art and design, and a good grasp of civil engineering. But did you know that mathematics forms the backbone of architectural theory and practice? In order to design a house, for example, or a store, an architect needs to be able to plan, calculate, and coordinate shapes, distances, and numerical relationships between spaces and the structures with which she plans to fill those spaces. To be successful, the architect must apply geometry and calculus to her designs in order to be able to make sure that the artistic vision will “work” in the real world. 441 442 C HAPTER 9 ■ Inverse Trigonometric, Hyperbolic, and Inverse Hyperbolic Functions Architects, engineers, and artists have been using math through the centuries in creating some of the world’s greatest treasures. The Great Pyramid at Giza (the only remaining member of the Seven Wonders of the World), Leonardo da Vinci’s “The Last Supper,” and the designs of Buck- minster Fuller (inventor of the geodesic dome) all feature complex geomet- ric formulations that required a strong command of mathematics in addition to an eye for form and function.

  • Geometry and Trigonometry
    Geometry and Trigonometry The names sine, secant and tangent are derived from the geometric terms associated with certain lines in the diagram below. If the radius of the circle is taken to be one unit, it follows that CN = sinθ, or CN = sinθ 1 AB = tanθ, or AB = tanθ 1 OB = secθ, or OB = secθ 1 The geometric narratives for these lines are- • The sine of an arc is a straight line drawn from one end of that arc, perpendicular to a diameter passing through the other end of the same arc. • The tangent of an arc is a straight line drawn from one extremity, perpendicular to the diameter, and terminated by a straight line drawn through the center of the circle and the other extremity of that arc. • The secant of an arc is a straight line drawn from the center of the circle, and produced till it meets the tangent. Now CN is half of the chord CD, and early expressions for the sines of angles were really lengths of the chords in a circle. The Arabic word for chord was translated into the Latin sinus. The lengths AB and OB are portions of the tangent and the secant to the circle. The trigonometric functions bearing these names were developed later than the sine, and they merely assumed the corresponding geometric names. The cofunctions received their names from the fact that any trigonometric function of an acute angle is equal in value to the cofunction of the complementary angle. There are other(old) functions that can also be reckoned.
