Functions of One Complex. Variable Third Edition Lars. Ahlfors Professor of. Express the result in symmetric form. We can now write equation 1. Express the fifth and tenth roots of unity in algebraic form.

Figure 1. The fifth roots of unity. The tenth roots of unity. Write the equation of an ellipse, hyperbola, parabola in complex form.

Let a and b be the foci of a hyperbola. Then when the magnitude of the difference of z and the foci is a constant, we will have a hyperbola. Prove that the diagonals of a parallelogram bisect each other and that the diagonals of a rhombus are orthogonal. Prove analytically that the midpoints of parallel chords to a circle lie on a diameter perpendicular to the chords. A cube has its vertices on the sphere S and its edges parallel to the coordinate axes.

Find the stereo- graphic projections of the vertices. Same problem for a regular tetrahedron in general position. Let Z, Z 0 denote the stereographic projections of z, z 0 , and let N be the north pole. Find the radius of the spherical image of the circle in the plane whose center is a and radius R.

If g w and f z are analytic functions, show that g f z is also analytic. Therefore, g f z satisfies the Cauchy- Riemann so it is analytic. Determine the conjugate harmonic function and the corresponding analytic function by integration and by the formal method. To find the harmonic conjugate v x, y, we need to look at the Cauchy-Riemann equations.

Then we can integrate with respect to y to find v x, y. Show that an analytic function cannot have a constant absolute value without reducing to a constant. Now, suppose that the matrix is invertible. We could also use the Cauchy-Riemann equations.

In order for both to be analytic, they both need to satisfy the Cauchy-Riemann equations. Suppose u z is harmonic. Then u z satisfies Laplace equation.

In particular, how are the zeros and poles related to each other? If R z is a rational function of order n, how large and how small can the order of R 0 z be? Let k be the degree of R z.

Prove that a convergent sequence is bounded. Show that the sum of an absolutely convergent series does not change if the terms are rearranged.

P P P Let an be an absolutely convergent series and bn be its rearrangement. Let P tn be the nth partial sum of bn. Let the remainder be rn. When the limit is one, we can draw no conclusion about convergence, but when the limit is greater than one, the sequence diverges. Thus, fn x is pointwise Pn convergent to f x. Select N such that this is true. It is easy if both series are absolutely convergent.

Try to rearrange the proof so economically that the absolute convergence of the second series is not needed. Then equation 2. What is the radius of convergence? Find the radius of convergence of the following power series: P For n!

P 2 For qn zn , we will use the root test. For zn! If an zn has a radius of convergence R, what is the radius of convergence of an z2n?

If an zn and bn zn have radii of convergence R1 and R2 , show that the radii of convergence of P an bn z is at least R1 R2. Therefore, an zn converges absolutely with a radius of convergence of R. Express them through cos iz and sin iz. Derive the addition formulas, and formulas for cosh 2z and sinh 2z. For real y, show that every remainder in the series for cos y and sin y has the same sign as the leading term this generalizes the inequalities used in the periodicity proof.

Find the real and imaginary parts of exp ez. Determine the real and imaginary parts of zz. Express arctan w in terms of the logarithm.

Since each root are angle multiplies about the origin, they will be n equally spaced points. The latter space is bounded in the sense that all distances lie under a fixed bound. By equation 3. Suppose that there are given two distance functions d x, y and d1 x, y on the same space S.

They are said to be equivalent if they determine the same open sets. Verify that this condition is fulfilled in exercise 1. A set is said to be discrete if all its points are isolated. Show that a discrete set in R or C is countable. Let S be a discrete set in R or C.

Therefore, S is countable. Show that the accumulation points of any set form a closed set. Let E be a set. Then E 0 is the set of accumulation limit points.
