Question

Find the real constants a and b so that the function f(z)=3x-y+5+i(ax+by-3)

Answer 1

Step-by-step explanation:

5737 is your answer.. ......

Answer 2

Answer:

a=1 and b=3

Step-by-step explanation:

if f(z) = 3x-y+5 +I(ax+by-3) should be analytic then

it should satisfy Cauchy- riemenn equation. ie,

Ux=Vy and Vx=-Uy

Here,

U= 3x-y+5, V=ax+by-3

Ux=3, Uy=-1

Vx=a, Vy=b

to satisfy CR eqn,

b=3 and a=1
