Answer:
13 + 7i
Step-by-step explanation:
We have given complex number
The difference of given complex number is:
(6 + 3i) - ( -7- 4i) = {6 - (- 7)} + {3 -( - 4)}i
⇒ 13 + 7i
Since the difference of two complex number (a + ib) and (c + id) is:
(a - c) + i(b - d)
Answer:
the answer is d

Answer:
The integral
is 0.
Step-by-step explanation:
A parameterization of curve C can be:
X (t) = cost 0 <= t <= pi
Y (t) = sint 0 <= t <= pi
r (t) = costi + sintj
r '(t) = -sinti + costj
![Fds = [-costsin^3t + sintcos^3t] dt](https://tex.z-dn.net/?f=Fds%20%3D%20%5B-costsin%5E3t%20%2B%20sintcos%5E3t%5D%20dt)
The integral
is given by:
![\int _0^{\pi }\left[-costsin^3t + sintcos^3t dt\right]dt](https://tex.z-dn.net/?f=%5Cint%20_0%5E%7B%5Cpi%20%7D%5Cleft%5B-costsin%5E3t%20%2B%20sintcos%5E3t%20dt%5Cright%5Ddt)
