Please answer without using previously posted answers. Thanks Let F(x, y) be a two-dimensional vector field. Spose further that there exists a scalar function, o, such that Then, F(x,y) is called a gradient field, and φ s called a potential function. Ideal Fluid Flow Let F represent the two-dimensional velocity field of an inviscid fluid that is incompressible, ie. . F-0 (or divergence-free). F can be represented by (1), where ф is called the velocity potential-show that o is harmonic....
Problem 1 Consider the composition f(w(z)) of two complex valued functions of a complex variable, f(w) and w(z), where z = x+iy and w=u+iv. Assume that both functions have continuous partial derivatives.

Problem (3) A function f(z) is analytic in the disk -1 where the modulus satisfies the bound Here b 2 a > 0 Find an optimal bound on |f'(0) in terms of a and b. Complete arguments required By optimal it is meant that (1) the bound holds for all functions with the stated property and (2) there actually is a function with the stated property such that the bound holds as an equality. The second part of this problem...
