c language. A complex number N is defined as: N = x + iy , where x is the real part and y is the imaginary part. The power of N is real and defined as: N^2 = x^2 + y^2, Write a function called cpower that returns the power of complex number. The function takes in x and y as double values and returns the power as a double value.
Question 3 (a) Write the following complex numbers z + iy in polar form z+ iy re giving the angle θ as the sum of its principal argument, (chosen to lie in-r < θ,-r) and an integer multiple of 2π. That is, write θ as θ θp + 2km where k-0, 1, 2, +2Tk +2T k +2T (b) Compute all three values of i1/S and write your answers in the form a + iy.
Complex affine transformation in plane s w = az+β, where:= x+iy, w = x, + iy'. For complex numbers α = αι + ia2, β = β1 + 2β2 rewrite this transformation as affine transformation in plane between coordi nates (x, y) and (x', y/). Identify corresponding linear 2x2 transforma- tion matrix A and translation vector t. Show that matrix representa- tion of this affine transformation is

f(z) = f(x+iy) = (x + 3xy - by ²x) + (y3 + 3x²y+y) Find all points Zec at which differentiable. Then, find all the points at which ZEC t is analytic.
Q5. (a) Consider the region in the complex plane defined by: z = x+iy : 1, lul π/3. Draw this region in the z-plane and mark a few points on it of your choice (eg, A, B, C) Now, apply the conformal transformation w-e*. Plot the resulting region and mark the corresponding points (eg., A, B, C.) (b) What is the area (in arbitrary square units) of the figure in the z-plane? What is the area in the w-plane?
Use the polar form of the complex number 5 i to find a value in Cartesian form, z = x+iy. Enter the exact answer. Z= 0+iv 5 Edit
(2 points) Here are several points on the complex plane: The red point represents the complex number zı = and the blue point represents the complex number Z2 = The "modulus" of a complex number z = x+iy, written [z], is the distance of that number from the origin: z) = x2 + y2. Find the modulus of zi. |zıl = 61^(1/2) We can also write a complex number z in polar coordinates (r, 6). The angle is sometimes called...

Hi, I really need help on both parts a and b of this Complex
Analysis question. Thanks!
1. Define exp(iy) := cos(y) + i sin(y). a. Prove, using trigonometry, that exp(iy+iy') = exp(iy). expliy') for y, y' ER two real numbers. b. Prove directly (using Taylor series for sin and cos) that expliy) = " where n! denotes the factorial of n. Hint: you may use the fact that an infinite sum of complex numbers an converges if and only...
