Calculate using Cauchys integral formula

zhuklara [117]

Answer:

9πi/2

Step-by-step explanation:

$\oint\limits_C {\frac{5z^{2}+4}{(z-1)(z+3)} } \, dz,\ C: |z|=2$

Let f(z) = (5z² + 4) / (z + 3).

$\oint\limits_C {\frac{f(z)}{z-1} } \, dz,\ C: |z|=2$

Using Cauchy's integral formula:

$2\pi i\ f(1)\\2\pi i\ (\frac{5(1)^{2}+4}{1+3}) \\2\pi i\ (\frac{9}{4}) \\\frac{9\pi i}{2}$

Let f(x) = x2- 3x - 7. Find f(-3)

Alexxx [7]

F(x) = x^2 - 3x - 7
f(-3) = (-3)^ 2 - 3(-3) - 7
f(-3) = 9 + 9 - 7
f(-3) = 18 - 7
f(-3) = 11
